Product Description
ROLLER CHAIN
Roller chain or bush roller chain is the type of chain drive most commonly used for transmission of mechanical power on many kinds of domestic, industrial and agricultural machinery, including conveyors, wire- and tube-drawing machines, printing presses, cars, motorcycles, and bicycles. It consists of a series of short cylindrical rollers held together by side links. It is driven by a toothed wheel called a sprocket. It is a simple, reliable, and efficient means of power transmission.
LUBRICATION
Many driving chains (for example, in factory equipment, or driving a camshaft inside an internal combustion engine) operate in clean environments, and thus the wearing surfaces (that is, the pins and bushings) are safe from precipitation and airborne grit, many even in a sealed environment such as an oil bath. Some roller chains are designed to have o-rings built into the space between the outside link plate and the inside roller link plates. Chain manufacturers began to include this feature in 1971 after the application was invented by Joseph Montano while working for Whitney Chain of Hartford, Connecticut. O-rings were included as a way to improve lubrication to the links of power transmission chains, a service that is vitally important to extending their working life. These rubber fixtures form a barrier that holds factory applied lubricating grease inside the pin and bushing wear areas. Further, the rubber o-rings prevent dirt and other contaminants from entering inside the chain linkages, where such particles would otherwise cause significant wear.[citation needed]
There are also many chains that have to operate in dirty conditions, and for size or operational reasons cannot be sealed. Examples include chains on farm equipment, bicycles, and chain saws. These chains will necessarily have relatively high rates of wear, particularly when the operators are prepared to accept more friction, less efficiency, more noise and more frequent replacement as they neglect lubrication and adjustment.
Many oil-based lubricants attract dirt and other particles, eventually forming an CHINAMFG paste that will compound wear on chains. This problem can be circumvented by use of a “dry” PTFE spray, which forms a solid film after application and repels both particles and moisture.
VARIANTS DESIGN

If the chain is not being used for a high wear application (for instance if it is just transmitting motion from a hand-operated lever to a control shaft on a machine, or a sliding door on an oven), then 1 of the simpler types of chain may still be used. Conversely, where extra strength but the smooth drive of a smaller pitch is required, the chain may be “siamesed”; instead of just 2 rows of plates on the outer sides of the chain, there may be 3 (“duplex”), 4 (“triplex”), or more rows of plates running parallel, with bushings and rollers between each adjacent pair, and the same number of rows of teeth running in parallel on the sprockets to match. Timing chains on automotive engines, for example, typically have multiple rows of plates called strands.
Roller chain is made in several sizes, the most common American National Standards Institute (ANSI) standards being 40, 50, 60, and 80. The first digit(s) indicate the pitch of the chain in eighths of an inch, with the last digit being 0 for standard chain, 1 for lightweight chain, and 5 for bushed chain with no rollers. Thus, a chain with half-inch pitch would be a #40 while a #160 sprocket would have teeth spaced 2 inches apart, etc. Metric pitches are expressed in sixteenths of an inch; thus a metric #8 chain (08B-1) would be equivalent to an ANSI #40. Most roller chain is made from plain carbon or alloy steel, but stainless steel is used in food processing machinery or other places where lubrication is a problem, and nylon or brass are occasionally seen for the same reason.
Roller chain is ordinarily hooked up using a master link (also known as a connecting link), which typically has 1 pin held by a horseshoe clip rather than friction fit, allowing it to be inserted or removed with simple tools. Chain with a removable link or pin is also known as cottered chain, which allows the length of the chain to be adjusted. Half links (also known as offsets) are available and are used to increase the length of the chain by a single roller. Riveted roller chain has the master link (also known as a connecting link) “riveted” or mashed on the ends. These pins are made to be durable and are not removable.
USE

Roller chains are used in low- to mid-speed drives at around 600 to 800 feet per minute; however, at higher speeds, around 2,000 to 3,000 feet per minute, V-belts are normally used due to wear and noise issues.
A bicycle chain is a form of roller chain. Bicycle chains may have a master link, or may require a chain tool for removal and installation. A similar but larger and thus stronger chain is used on most motorcycles although it is sometimes replaced by either a toothed belt or a shaft drive, which offer lower noise level and fewer maintenance requirements.
The great majority of automobile engines use roller chains to drive the camshaft(s). Very high performance engines often use gear drive, and starting in the early 1960s toothed belts were used by some manufacturers.
Chains are also used in forklifts using hydraulic rams as a pulley to raise and lower the carriage; however, these chains are not considered roller chains, but are classified as lift or leaf chains.
Chainsaw cutting chains superficially resemble roller chains but are more closely related to leaf chains. They are driven by projecting drive links which also serve to locate the chain CHINAMFG the bar.

A perhaps unusual use of a pair of motorcycle chains is in the Harrier Jump Jet, where a chain drive from an air motor is used to rotate the movable engine nozzles, allowing them to be pointed downwards for hovering flight, or to the rear for normal CHINAMFG flight, a system known as Thrust vectoring.
WEAR
The effect of wear on a roller chain is to increase the pitch (spacing of the links), causing the chain to grow longer. Note that this is due to wear at the pivoting pins and bushes, not from actual stretching of the metal (as does happen to some flexible steel components such as the hand-brake cable of a motor vehicle).
With modern chains it is unusual for a chain (other than that of a bicycle) to wear until it breaks, since a worn chain leads to the rapid onset of wear on the teeth of the sprockets, with ultimate failure being the loss of all the teeth on the sprocket. The sprockets (in particular the smaller of the two) suffer a grinding motion that puts a characteristic hook shape into the driven face of the teeth. (This effect is made worse by a chain improperly tensioned, but is unavoidable no matter what care is taken). The worn teeth (and chain) no longer provides smooth transmission of power and this may become evident from the noise, the vibration or (in car engines using a timing chain) the variation in ignition timing seen with a timing light. Both sprockets and chain should be replaced in these cases, since a new chain on worn sprockets will not last long. However, in less severe cases it may be possible to save the larger of the 2 sprockets, since it is always the smaller 1 that suffers the most wear. Only in very light-weight applications such as a bicycle, or in extreme cases of improper tension, will the chain normally jump off the sprockets.
The lengthening due to wear of a chain is calculated by the following formula:
M = the length of a number of links measured
S = the number of links measured
P = Pitch
In industry, it is usual to monitor the movement of the chain tensioner (whether manual or automatic) or the exact length of a drive chain (one rule of thumb is to replace a roller chain which has elongated 3% on an adjustable drive or 1.5% on a fixed-center drive). A simpler method, particularly suitable for the cycle or motorcycle user, is to attempt to pull the chain away from the larger of the 2 sprockets, whilst ensuring the chain is taut. Any significant movement (e.g. making it possible to see through a gap) probably indicates a chain worn up to and beyond the limit. Sprocket damage will result if the problem is ignored. Sprocket wear cancels this effect, and may mask chain wear.
CHAIN STRENGTH
The most common measure of roller chain’s strength is tensile strength. Tensile strength represents how much load a chain can withstand under a one-time load before breaking. Just as important as tensile strength is a chain’s fatigue strength. The critical factors in a chain’s fatigue strength is the quality of steel used to manufacture the chain, the heat treatment of the chain components, the quality of the pitch hole fabrication of the linkplates, and the type of shot plus the intensity of shot peen coverage on the linkplates. Other factors can include the thickness of the linkplates and the design (contour) of the linkplates. The rule of thumb for roller chain operating on a continuous drive is for the chain load to not exceed a mere 1/6 or 1/9 of the chain’s tensile strength, depending on the type of master links used (press-fit vs. slip-fit)[citation needed]. Roller chains operating on a continuous drive beyond these thresholds can and typically do fail prematurely via linkplate fatigue failure.
The standard minimum ultimate strength of the ANSI 29.1 steel chain is 12,500 x (pitch, in inches)2. X-ring and O-Ring chains greatly decrease wear by means of internal lubricants, increasing chain life. The internal lubrication is inserted by means of a vacuum when riveting the chain together.

Standards organizations (such as ANSI and ISO) maintain standards for design, dimensions, and interchangeability of transmission chains. For example, the following Table shows data from ANSI standard B29.1-2011 (Precision Power Transmission Roller Chains, Attachments, and Sprockets) developed by the American Society of Mechanical Engineers (ASME). See the references[8][9][10] for additional information.

For mnemonic purposes, below is another presentation of key dimensions from the same standard, expressed in fractions of an inch (which was part of the thinking behind the choice of preferred numbers in the ANSI standard):
| Pitch (inches) | Pitch expressed in eighths |
ANSI standard chain number |
Width (inches) |
|---|---|---|---|
| 1⁄4 | 2⁄8 | 25 | 1⁄8 |

| 1⁄2 | 4⁄8 | 40 | 5⁄16 |
| 5⁄8 | 5⁄8 | 50 | 3⁄8 |
| 3⁄4 | 6⁄8 | 60 | 1⁄2 |
| 1 | 8⁄8 | 80 | 5⁄8 |
Notes:
1. The pitch is the distance between roller centers. The width is the distance between the link plates (i.e. slightly more than the roller width to allow for clearance).
2. The right-hand digit of the standard denotes 0 = normal chain, 1 = lightweight chain, 5 = rollerless bushing chain.
3. The left-hand digit denotes the number of eighths of an inch that make up the pitch.
4. An “H” following the standard number denotes heavyweight chain. A hyphenated number following the standard number denotes double-strand (2), triple-strand (3), and so on. Thus 60H-3 denotes number 60 heavyweight triple-strand chain.
A typical bicycle chain (for derailleur gears) uses narrow 1⁄2-inch-pitch chain. The width of the chain is variable, and does not affect the load capacity. The more sprockets at the rear wheel (historically 3-6, nowadays 7-12 sprockets), the narrower the chain. Chains are sold according to the number of speeds they are designed to work with, for example, “10 speed chain”. Hub gear or single speed bicycles use 1/2″ x 1/8″ chains, where 1/8″ refers to the maximum thickness of a sprocket that can be used with the chain.
Typically chains with parallel shaped links have an even number of links, with each narrow link followed by a broad one. Chains built up with a uniform type of link, narrow at 1 and broad at the other end, can be made with an odd number of links, which can be an advantage to adapt to a special chainwheel-distance; on the other side such a chain tends to be not so strong.
Roller chains made using ISO standard are sometimes called as isochains.

Can car parking chains be retrofitted into existing parking facilities to upgrade their security measures?
Yes, car parking chains can be retrofitted into existing parking facilities to upgrade their security measures and access control. Retrofitting parking chains is a practical and cost-effective solution for improving security without the need for major infrastructure changes. Here’s how it can be done:
1. Site Assessment: Conduct a thorough site assessment to identify suitable locations for installing the parking chains. Consider factors such as traffic flow, vehicle types, and entry/exit points.
2. Choose the Right Chains: Select parking chains that are compatible with the existing facility and meet the security requirements. Consider factors like traffic volume, weather resistance, and automation options.
3. Anchor Points: Identify and prepare sturdy anchor points on either side of the entrance or exit where the chains will be installed. Ensure the anchors are securely attached to the ground or wall.
4. Installation: Install the parking chains according to the manufacturer’s instructions, ensuring proper tension and alignment. Consider automatic systems for smoother access control.
5. Integration with Access Control: If using automated parking chains, integrate them with access control systems like key cards, remote controls, or license plate recognition technology.
6. Signage: Install clear signage to inform users about the presence of parking chains and how to operate them.
7. Testing: Test the parking chains’ movement to ensure they raise and lower smoothly without obstructions or jams.
8. Training: Provide training to parking attendants or personnel responsible for operating the chains to ensure proper use and maintenance.
9. Regular Maintenance: Develop a maintenance schedule and conduct regular inspections to keep the parking chains in good working condition.
10. Consider Advanced Features: Depending on the facility’s requirements, consider retrofitting smart parking chains with advanced features like mobile app integration or reservation systems for enhanced security and convenience.
Retrofitting car parking chains allows existing parking facilities to upgrade their security measures efficiently, enhancing access control and providing a safer parking environment for users.
What are the maintenance requirements for car parking chains to ensure smooth operation over time?
Regular maintenance is essential to ensure the smooth operation and longevity of car parking chains. Proper care and attention will help prevent malfunctions and ensure reliable access control in parking facilities. Here are the key maintenance requirements:
1. Cleaning: Regularly clean the parking chains to remove dirt, dust, and debris that can accumulate over time. Clean chains ensure smooth movement and prevent unnecessary wear.
2. Lubrication: Apply appropriate lubrication to the chain links and any moving parts of the chain mechanism. Lubrication reduces friction and wear, allowing the chain to move smoothly.
3. Inspection: Conduct routine inspections of the parking chains to identify any signs of wear, damage, or misalignment. Promptly address any issues to prevent further damage and ensure optimal performance.
4. Adjustments: Check the tension and alignment of the chains regularly. Make necessary adjustments to ensure the chain remains properly tensioned and aligned.
5. Replacement of Worn Parts: If any components of the parking chain show significant wear or damage, replace them promptly to maintain the chain’s integrity and functionality.
6. Weather Protection: Apply protective coatings or paint to steel chains to minimize the impact of weather elements and reduce the risk of corrosion.
7. Addressing Corrosion: For chains made of materials susceptible to corrosion, such as steel, regularly inspect for signs of rust and treat affected areas to prevent further corrosion.
8. Preventing Obstructions: Ensure that the area around the parking chains is clear of any obstacles that could hinder their movement or cause damage.
9. Training and Education: Train parking attendants or personnel responsible for operating the parking chains to handle them properly and conduct basic maintenance tasks.
10. Regular Testing: Periodically test the raising and lowering mechanism of the parking chains to verify that they are functioning correctly.
By adhering to these maintenance requirements, parking facility managers can ensure the smooth operation and reliability of car parking chains, minimizing downtime and ensuring efficient access control for vehicles in the long run.
How do car parking chains enhance security and prevent unauthorized access to parking areas?
Car parking chains serve as a physical barrier and play a crucial role in enhancing security and preventing unauthorized access to parking areas. Here’s how they achieve this:
1. Physical Deterrent: The presence of a chain across the entrance acts as a visual deterrent, dissuading unauthorized vehicles from attempting to enter the parking area. It signals that the area is controlled and restricted to authorized personnel only.
2. Controlled Access: Parking chains are manually operated or integrated with electronic access control systems. Only authorized users with the appropriate credentials, such as a key, keycard, or remote control, can raise or lower the chain to gain access.
3. Preventing Tailgating: In manual systems, parking attendants can visually verify each vehicle’s authorization before allowing entry. In automatic systems, the access control technology ensures that only one vehicle is allowed to pass at a time, preventing unauthorized vehicles from tailgating behind an authorized one.
4. Flexible Access Control: Some parking chains can be integrated with electronic access control systems that allow for fine-grained control. This includes time-based access permissions or specific access rights for different user groups, enhancing security measures.
5. Cost-Effective Security: Compared to more advanced access control systems like automated gates or barrier arms, parking chains offer a cost-effective security solution, making them suitable for various parking facilities.
6. Reducing Vehicle Theft: By restricting access to only authorized vehicles, parking chains reduce the risk of theft or unauthorized use of parked vehicles.
7. Minimizing Traffic Violations: Parking chains prevent unauthorized parking, reducing instances of illegal parking or traffic violations within the parking area.
8. Additional Security Measures: Parking chains can be complemented with other security features like surveillance cameras, lighting, and manned security personnel, creating a comprehensive security strategy for the parking facility.
In summary, car parking chains provide a simple yet effective method to control access, enhance security, and prevent unauthorized entry into parking areas, ensuring a safer and more controlled environment for vehicles and users.

Standards organizations (such as ANSI and ISO) maintain standards for design, dimensions, and interchangeability of transmission chains. For example, the following Table shows data from ANSI standard B29.1-2011 (Precision Power Transmission Roller Chains, Attachments, and Sprockets) developed by the American Society of Mechanical Engineers (ASME). See the references[8][9][10] for additional information.

For mnemonic purposes, below is another presentation of key dimensions from the same standard, expressed in fractions of an inch (which was part of the thinking behind the choice of preferred numbers in the ANSI standard):
| Pitch (inches) | Pitch expressed in eighths |
ANSI standard chain number |
Width (inches) |
|---|---|---|---|
| 1⁄4 | 2⁄8 | 25 | 1⁄8 |
| 3⁄8 | 3⁄8 | 35 | 3⁄16 |
| 1⁄2 | 4⁄8 | 41 | 1⁄4 |
| 1⁄2 | 4⁄8 | 40 | 5⁄16 |
| 5⁄8 | 5⁄8 | 50 | 3⁄8 |
| 3⁄4 | 6⁄8 | 60 | 1⁄2 |
| 1 | 8⁄8 | 80 | 5⁄8 |
Notes:
1. The pitch is the distance between roller centers. The width is the distance between the link plates (i.e. slightly more than the roller width to allow for clearance).
2. The right-hand digit of the standard denotes 0 = normal chain, 1 = lightweight chain, 5 = rollerless bushing chain.
3. The left-hand digit denotes the number of eighths of an inch that make up the pitch.
4. An “H” following the standard number denotes heavyweight chain. A hyphenated number following the standard number denotes double-strand (2), triple-strand (3), and so on. Thus 60H-3 denotes number 60 heavyweight triple-strand chain.
A typical bicycle chain (for derailleur gears) uses narrow 1⁄2-inch-pitch chain. The width of the chain is variable, and does not affect the load capacity. The more sprockets at the rear wheel (historically 3-6, nowadays 7-12 sprockets), the narrower the chain. Chains are sold according to the number of speeds they are designed to work with, for example, “10 speed chain”. Hub gear or single speed bicycles use 1/2″ x 1/8″ chains, where 1/8″ refers to the maximum thickness of a sprocket that can be used with the chain.
Typically chains with parallel shaped links have an even number of links, with each narrow link followed by a broad one. Chains built up with a uniform type of link, narrow at 1 and broad at the other end, can be made with an odd number of links, which can be an advantage to adapt to a special chainwheel-distance; on the other side such a chain tends to be not so strong.
Roller chains made using ISO standard are sometimes called as isochains.

Can car parking chains be integrated with access control systems, such as key cards or remote controls?
Yes, car parking chains can be integrated with access control systems, allowing for more efficient and convenient vehicle access in parking facilities. Integration with access control systems offers several benefits:
1. Key Cards: Parking chains can be linked to electronic access control systems that use key cards or RFID tags. Authorized users are provided with key cards that they can swipe or tap at the entrance to raise the chain, granting them access to the parking area.
2. Remote Controls: In automated parking chains, remote controls can be used to raise or lower the chains. This is particularly useful for parking attendants or personnel who can remotely manage vehicle access from a central location, reducing the need for physical presence at the entrance.
3. Electronic Passes: Some parking facilities issue electronic passes to authorized users. These passes can be read by sensors at the entrance, automatically raising the chain to allow access without the need for manual operation.
4. License Plate Recognition: Advanced access control systems may use license plate recognition technology to automatically identify and grant access to pre-registered vehicles as they approach the entrance, eliminating the need for physical cards or passes.
5. Time-Based Access: Access control systems can be configured to grant access only during specific times or days. This is particularly useful for parking facilities with restricted access hours or reserved parking spaces for certain users.
6. Enhanced Security: Integration with access control systems improves security by ensuring that only authorized vehicles can enter the parking area, reducing the risk of unauthorized access or parking violations.
7. Efficient Traffic Management: Automated access control systems can process vehicles more quickly, reducing waiting times and traffic congestion at the entrance during peak hours.
By integrating car parking chains with access control systems, parking facilities can enhance security, improve user experience, and efficiently manage vehicle access, making it a popular choice for modern parking facilities.
What are the maintenance requirements for car parking chains to ensure smooth operation over time?
Regular maintenance is essential to ensure the smooth operation and longevity of car parking chains. Proper care and attention will help prevent malfunctions and ensure reliable access control in parking facilities. Here are the key maintenance requirements:
1. Cleaning: Regularly clean the parking chains to remove dirt, dust, and debris that can accumulate over time. Clean chains ensure smooth movement and prevent unnecessary wear.
2. Lubrication: Apply appropriate lubrication to the chain links and any moving parts of the chain mechanism. Lubrication reduces friction and wear, allowing the chain to move smoothly.
3. Inspection: Conduct routine inspections of the parking chains to identify any signs of wear, damage, or misalignment. Promptly address any issues to prevent further damage and ensure optimal performance.
4. Adjustments: Check the tension and alignment of the chains regularly. Make necessary adjustments to ensure the chain remains properly tensioned and aligned.
5. Replacement of Worn Parts: If any components of the parking chain show significant wear or damage, replace them promptly to maintain the chain’s integrity and functionality.
6. Weather Protection: Apply protective coatings or paint to steel chains to minimize the impact of weather elements and reduce the risk of corrosion.
7. Addressing Corrosion: For chains made of materials susceptible to corrosion, such as steel, regularly inspect for signs of rust and treat affected areas to prevent further corrosion.
8. Preventing Obstructions: Ensure that the area around the parking chains is clear of any obstacles that could hinder their movement or cause damage.
9. Training and Education: Train parking attendants or personnel responsible for operating the parking chains to handle them properly and conduct basic maintenance tasks.
10. Regular Testing: Periodically test the raising and lowering mechanism of the parking chains to verify that they are functioning correctly.
By adhering to these maintenance requirements, parking facility managers can ensure the smooth operation and reliability of car parking chains, minimizing downtime and ensuring efficient access control for vehicles in the long run.
What is a car parking chain, and how is it used in parking facilities and garages?
A car parking chain is a mechanical barrier used in parking facilities and garages to control vehicle access and prevent unauthorized entry. It consists of a sturdy metal chain suspended across the entrance or exit of a parking area.
The chain is connected to two sturdy posts or walls on either side of the entrance. When lowered, the chain obstructs the passage of vehicles, restricting their entry or exit. Conversely, when lifted, it allows authorized vehicles to pass through.
Parking chains are commonly used in places where a more sophisticated access control system like a gate or a barrier arm may not be necessary. They offer a simple and cost-effective solution for managing vehicle flow.
Typically, parking facility attendants or authorized personnel are responsible for controlling the car parking chain. They manually raise and lower the chain using a key or a specialized lock system.
In some cases, modern parking chains may be automated and integrated with access control systems. This can include keycard readers, electronic passes, or even remote-controlled mechanisms, making it more convenient for authorized users to enter and exit the parking area.
Overall, car parking chains serve as a physical deterrent to prevent unauthorized access and ensure better control over vehicle movement in parking facilities and garages.

Different types of drive chains
Drive chains are an important part of many different types of machinery. In this article, we’ll cover a variety of different types, from square links to engineered steel. From there, we’ll discuss different types of chains, such as double and leaf chains. Let’s take a closer look at each one. Once you know what kind of chain you’re looking for, you can make a buying decision. If you’re not sure where to start, read on to learn more about these types of chains, what to look for when choosing, and how to choose the right chain for your specific application.
Engineering Steel Chain
Engineering steel chains are widely used in conveyors, bucket elevators, tensioning links, transmission chains, etc., and have the characteristics of high strength, low friction, and good shock resistance. Early models of these chains were developed for difficult-to-convey applications. They were originally made of all-steel components with flanged rollers made of cast iron. They then increase in size, strength, and spacing in response to the heavy-duty requirements of the industry.
Today, these chains are used in a wide variety of applications, including tough oil drilling operations and forklifts. They offer excellent durability and high power transfer and are available in a variety of materials. They are also ideal for harsh environments such as harsh oil drilling. Their high-strength steel construction means they can handle harsh operating conditions. Their durability is an essential feature of any chain, and CZPT Chains offers a full line of engineered steel chains to meet your exact specifications.
A drive chain made of engineered steel consists of several components: links, pin joints, and sprockets. This allows them to carry heavy loads with minimal stretch. Due to its internal mechanical advantage, the chain runs around the sprockets with almost 100% efficiency. Also, the chain is made of special steel that can withstand certain conditions. They are available in different alloys and grades. If you have any questions, please feel free to contact us.
Roller chain wear is a major problem for conveyor and drive chains. In these cases, the rollers of the chain are more prone to wear than the bushings, so lubrication is essential. Many chains are designed to work with little or no lubrication. Finally, material selection is an important factor in the design of engineered steel conveyor chains. These factors will help ensure that the chain stays in good shape.
Conveyor Chains with Square Links
There are two basic types of conveyor chains. The first is the square chain, commonly used in cranes and hoists. It’s cheap to manufacture but more prone to overload. The second is a chain that uses hook joints or detachable links. These are used for short-term power transmission and have a lubricating effect. Usually, they are made of malleable iron but can be more expensive.
Another type of chain is the removable steel chain. For moderate loads, this is an easy-to-install option. The closed end of the tab should face the sprocket. It is very important to maintain the alignment of the chain relative to the sprockets. The chain should be adjusted to suit the load before installation. It is important to keep the chain lubricated to prolong its life.
Steel chains offer a wider selection of materials and heat treatments. This chain is also more accurate than its counterpart. Steel bushing chains are less expensive but require more frequent lubrication. Steel roller chains are often used for long conveyor centers or high loads. However, lower friction requirements require lower strength chains. This means that chains with square links are a better choice for smaller conveyors. But this style has its drawbacks.
Bushing chains are made of steel and are an excellent alternative for small-scale applications. The pins are silent and prevent tooth damage. Bushed roller chains are also used to a certain extent as conveyor chains. However, the main advantage of the bushing roller chain is that it does not make any noise at all. Bushed roller chains are made of alloy steel and are suitable for very low-speed applications.
double chain
Double-strand roller chain, also known as a double-strand, consists of two rows of single-strand links. It has high impact strength, low weight, and a small form factor. Duplex roller chains are manufactured using CZPT technology, which uses solid rollers to improve sprocket tooth rotation and reduce shock loads. During the manufacturing process, the metal is heat-treated to increase strength and reduce corrosion.
A single chain is designed for a single sprocket, while a double chain consists of two identical chains connected side by side. Double chains are more durable than simple chains because double rollers contain roller bearings, pins, and other components. Simplex drive chains can handle high loads, while duplex drive chains are designed for medium-duty applications.
leaf chain
Blade chains are used in reciprocating devices such as forklifts. They are also used in machine tools for counterweight chains. Leaf chains come in a variety of lengths, usually with female or male ends. Leaf chains can be manufactured in even or odd pitches and are ideal for lifting and balancing. This article will introduce some key uses of leaf chains in drive chains. Additionally, we’ll discuss how they are made and how they behave in applications.
Most drive chains today are made from leaf chains. These chains are designed to increase the strength of the chain. However, they are less expensive than other types of chains. You can also purchase specialized leaf chains for certain applications. CZPT Chain also offers custom leaf chains for your unique needs. Leaf chains are commonly used in forklifts, material handling, and lifting applications. They are usually made from high-quality components. The BL1688 Leaf Chain has 8 x 8 laces and is sold in 10-foot boxes or 25- to 100-foot reels. The leaf chain can be cut as needed.
When selecting a leaf chain for a specific application, consider the minimum tensile strength of the chain. The minimum breaking strength must be high enough to protect the worker or machine, but must also be legal for the type of machine. Most manufacturers publish this minimum strength requirement. To make the most durable leaf chain, design engineers must consider the ISO4347 standard when choosing the right leaf chain. Leaf chain manufacturers tend to exceed international standards by about 20%.
roller chain
Roller chains are made from a variety of materials. Some common materials include steel and stainless steel. The most suitable material depends on cost, environmental conditions, and horsepower transmission design. Chain manufacturers can optimize the material for the intended use. Depending on its size, spacing, and special construction techniques, it can be made lighter or heavier. This is an advantage for applications in noise-sensitive environments. Below are some examples of common uses for roller chains.
The wear of the components in a roller chain is an unavoidable part of its operation. The amount of elongation depends on factors such as lubrication, load, and the frequency of articulation between the pin and bushing. Manufacturing critical wear parts require careful attention to detail. Proper raw materials, manufacturing, and assembly are critical to product performance and longevity. If these components aren’t of high quality, they won’t last as long as the chain should.
The industry recommends measuring the wear elongation of the roller chain to determine when it needs to be replaced. Proper safety procedures must be used to measure chain tension. The tight span of the chain shall be measured by applying the measuring load specified by ANSI. A correctly measured roller chain is safe to use. For motorcycles, the chain is bigger and stronger. Often, toothed belts are replaced by shaft drives because they are less noisy and require less maintenance.
Tensile strength is the most commonly used measurement method for roller chains. This measurement represents the amount of load the chain can withstand before it breaks. Fatigue strength is another measure of durability. Fatigue strength measures how long a roller chain can withstand long-term use before failing. These two measurements are closely related and maybe the same or different. In addition to tensile strength, fatigue strength is a useful factor to consider when purchasing a chain.

Roller Chain Basics
Before choosing the right roller chain for your machine, it is necessary to learn some basics. Learn about sprockets, tensile strength, pitch, and width. Read this article to learn more. It will help you make an informed decision. Getting the right product is critical, but it’s not always as simple as choosing a brand name. You need to choose a company that supports its products and provides good service.
Roller sprocket
If you are planning to purchase roller sprockets for your application, you should first look at the various types available. Sprockets available for single-strand roller chains are manufactured by Boston Steel – Type B sprockets are drilled to size. They are available in 1/4, 3/8, 1/2, 5/8, 3/4 and 1″ pitch sizes.
The diameter of the sprocket is important when choosing the right sprocket for your application. Using a caliper to measure the diameter of a toothless plate is a good way to determine the exact size of the sprocket. A caliper is the diameter of a plate without teeth. On Type B and C sprockets, the hub diameter measures the thickness of the hub.
Another type of sprocket is the steel split sprocket, which is split in diameter. This type is easy to install and remove, and is held together by bolts in the hub. Typically, split sprockets have chain pitches ranging from 40 to 240 and bores ranging from 3/4″ to 6″. The split sprockets are designed with one pointing towards the ceiling and the other two parallel to the floor.
When shopping for sprockets, it is important to remember that they are designed specifically for a specific chain. All chains are manufactured to specific standards. In the United States, the most common standard is ANSI. The chain pitch is the distance between the center of each pin and the center of the next pin. In the US, the standard is always measured in eight-inch intervals.
In addition to sprocket size, sprocket pitch and the surface area also affect chain life. Unlike belt sprockets, which are made of forged steel, the teeth on roller sprockets are stamped from steel sheet or pressed from powdered metal. The harder the teeth, the longer the chain will last.
Roller chain pitch
The pitch of a roller chain is the distance between the sprocket and the pin. The smaller the thread pitch, the smaller the bushing wear. Generally speaking, the smaller the pitch, the longer the life of the chain. For best performance and longest life, manufacturers recommend a minimum chain pitch of 2% to 3%. Chain pitch is important to ensure proper performance, and the manufacturer recommends that you replace the chain when it reaches 2% to 3% of normal.
To determine the correct chain pitch for a particular chain, first determine the sprocket size and pitch. Pitch is the distance between pin centers, measured in 1/8 inch increments. The pin diameter of the chain is also important. If you’re not sure about the pin diameter of your chain, measure a few links to get a good average reading. Alternatively, use a caliper to measure the inside diameter of the sprocket and count the number of teeth.
When sizing a sprocket, measure the chain between the gears with a caliper and compare it to the measurements on the chain size chart. Make sure you have checked all the specs and checked the correct chain pitch. Then, choose the correct chain pitch for your needs. This is a critical step in choosing the right chain. So get the correct pitch for your roller chain. Correct pitch helps ensure maximum performance and safety.
To identify a specific type of roller chain, measure its tensile strength. This represents the amount of load the chain can withstand before breaking. Another key parameter to consider is fatigue strength. Chains with high fatigue strength are more resistant to rust and wear than chains with low fatigue strength. The numbers on the right in the standard numbering represent normal or light duty chains, while the numbers on the left represent the pitch of heavy-duty chains.
Double pitch roller chains are a variant of single pitch chains. They are manufactured according to ISO 606 and meet the same standards as single pitch chains. They are mainly used in applications with lower requirements for speed and power transmission. The plates of double pitch roller chains are also longer than single pitch chains. The double pitch drive series is also used for elevator and long conveyor drives. There are three main types of roller chains: single-pitch chains, double-pitch carriers, and oversized rollers.
Roller chain width
When buying a roller chain, one of the first decisions you must make is its width. To make this determination, you need to measure the overall width of the chain, the diameter, and the width of each roller. You must also know the height and thickness of the board. After taking these measurements, you can start shopping for the perfect roller chain. But before you buy a new chain, it’s important to know what to expect from the chain itself.
There are many different types of roller chains. These chains are available for ANSI and metric measurements. They come in single-stranded and double-stranded variants. They are usually used for power transmission. Other types include agricultural, automotive, conveyor, multi-strand, and four-strand chains. These charts also include a chart so you can easily see the exact size you need. Listed below are some of the benefits of buying a roller chain.
Roller diameter and pin diameter are important factors in choosing the correct chain width. The width of the chain is the nearest binary fraction of 5/8 of an inch. It should be at least half the thickness of the sprocket, and the plate thickness is one-eighth the width of the chain. Overweight chains are indicated with the suffix H. The pitch and width of the chain are determined by the working load and machine speed.
The outer links of the roller chain are called pin links. These pins are inserted into the bushings of the adjacent roller links. They are held in place by cotter pins. Pin links are usually pressed into the pins of heavy-duty chains. These pins are used to hold the rollers in place. However, these pin chains can reduce the power rating of roller chains by up to 20%.
The ANSI 29.1 Steel Chain Specification specifies a minimum pitch in inches and ultimate strength of 12,500 x pitch in inches. At the same time, the O-ring chain greatly reduces wear due to its lubricating effect. O-ring and X-ring chains contain a lubricant injected by vacuum when riveting the chain together. Transmission chains are tested and governed by standards bodies such as ANSI. In 2011, the American Society of Mechanical Engineers developed a standard for precision power transmission chains.
Roller chain tensile strength
One of the most important indicators of roller chain strength is tensile strength. This measurement refers to the amount of load the chain can withstand before breaking. Another measure, called fatigue strength, refers to the maximum load a chain can withstand before it breaks. The strength of a roller chain depends on its size, the quality of the steel used in its construction, and the heat treatment. There are also differences in the types of shot peening used to treat steel, pitch holes, and link plates.
When choosing a roller chain, the workload is critical. This is the maximum load the chain can withstand before fatigue failure occurs. This measurement is critical because it helps determine the type of load applied to the chain. When deciding which roller chain to buy, be sure to consider the mechanical type and desired strength. Then, make sure it meets strength and load-carrying capacity requirements.
The ultimate tensile strength of a roller chain is based on the manufacturer’s recommended maximum tensile strength. However, the actual tensile strength may be higher or lower than this value. The working load limit of a roller chain can also be calculated by multiplying the chain diameter by the grade. The working load limit of a chain is the highest tension it can withstand before breaking. This value is usually expressed in points.
The maximum tensile strength of roller chains varies by chain type. The single-strand heavy chain has thick side plates for higher shock loads. Single strand heavy-duty roller chains, also known as “bushing” roller chains, are also available. Double-stranded heavy chains are structurally similar, but they have two layers of steel connected by pins that are nearly twice as strong as standard roller chains.
The tensile strength of a single-strand roller chain is approximately 500 tons. In comparison, a single-chain blockchain has a tensile strength of 900. The tensile strength of the two is similar, and it is not recommended to choose one or the other. Although steel and titanium chains are considered the strongest materials for roller chains, these materials are not magnetic.

Advantages and disadvantages of roller chains
If you need to lift heavy objects, you should know how to use a roller chain. Its simple design and simplicity make it ideal for a wide range of applications. This article will discuss the advantages and different types of applications of roller chains. After reading this article, you will be able to choose the type of roller chain that best suits your specific needs. In the next section, we’ll discuss how to deal with it.
Put on
How to measure the wear of a roller chain? There are several methods available, but the most accurate is to use a wear gauge kit. The CZPT Chain Wear Indicator Kit measures chain elongation. Compliant with ANSI and British Standards, this tool is critical to the industry chain and can help you determine when replacement is required. Improper chain maintenance can cause equipment to slip or perform poorly, resulting in unnecessary downtime.
In addition to measuring the elongation of the roller chain, it is also possible to measure the pitch of the rollers. This measurement represents the ANSI #80 standard for roller chains. Vernier calipers can also be used to measure the pitch of chains. This tool is very useful and also acts as a bottle opener. You can even use it as a wear gauge. This way, you can determine if the roller chain needs to be replaced.
The wear resistance of a roller chain can extend its life by 10% or more. However, proper lubrication and general maintenance are essential to ensure the longest lifespan of your chain. The manufacturing process of a roller chain assembly also plays a crucial role in determining its service life. For longer life, you might consider purchasing a heavy-duty series roller chain with thicker side plates and longer pins. If you need greater working load capacity, you can also consider heavy-duty chains.
High-quality components are critical to the longevity of the roller chain. High-quality roller chain components require precise heat treatment processes. The use of proprietary steel allows the company to manufacture more durable drums. The pins are manufactured to tight tolerances and then undergo a centerless grinding process. This process removes any surface defects, resulting in a mirror finish on the pins. The uniformity of this surface finish also ensures that the load is evenly distributed on the pins, extending the life of the chain.
Material
Among the materials used in roller chains, carbon steel and alloy steel are the most common. However, stainless steel is used in food processing equipment and applications that require lubrication. Other materials used for roller chains include nylon and brass. For more information, see the USACE Material Specification Sheet for more information. You can also find information about the performance of a roller chain by its design. But before choosing one of these materials, consider its pros and cons.
Stainless steel is an excellent choice for roller chains. It is corrosion-resistant and can operate in extreme temperatures without cracking. Stainless steel is a non-magnetic material that can operate in a temperature range of -200 degrees to +700 degrees Fahrenheit. In addition to its corrosion-resistant properties, stainless steel can withstand a variety of environments and can be used in heavy-duty applications. The MEGA series is the strongest stainless steel roller chain in the world.
Application
As the name suggests, a roller chain has 5 basic components: pins, bushings, rollers, and pin chainplates. These components are precision engineered to ensure optimum performance and durability. Typical applications include drives and conveyor belts. The various components of the roller chain can be customized to specific needs. Read on to learn more about how these parts work together. This article presents the advantages and disadvantages of different types of roller chains and discusses their applications.
A roller chain is a form of chain drive consisting of short cylindrical rollers connected together by side links and gears called sprockets. While these devices are simple, they have some limitations. In most cases, sprockets must be designed with a maximum tensile load on one tooth to prevent premature chain failure. Therefore, these chains are less efficient than belt drives with higher inertia.
Roller chains are usually made of carbon or alloy steel, although stainless steel is often used where food processing machinery and lubrication are problematic. Sometimes, nylon and brass are used. The maximum running speed of the roller chain is important for some applications, but it also provides economic benefits for users and manufacturers. The maximum running speed of a roller chain is usually governed by a wear limit, which can vary by application.
The global roller chain market is expected to grow at a CAGR of over 5.4% over the next six years. The research report covers the competitive landscape and key factors influencing the market. The report also analyzes the growth potential, product utilization, and pricing models of key vendors. It also covers the SWOT analysis of the key players in the industry. The study provides a comprehensive market analysis of all these factors and more. It also highlights key players and their strategies and identifies the fastest growing regions for their products and services.
Maintain
Because rollers are exposed to a variety of environments, including snow, rain, and muddy roads, regular maintenance is required to prevent damage. Because they must encounter these elements frequently, frequent inspections are important to prevent rust and other damage. Also, avoid pouring acidic or alkaline cleaning products on the roller chain. Instead, use hot water with hand sanitizer or a disposable toothbrush to clean the rollers. Washing the chain directly with water has little effect.
For small rollers, the workload during the break-in period should not be too large, otherwise, it will cause overheating. The small drum should also be inspected frequently for any unusual appearance, which may indicate that the system is not functioning properly. In this case, the operation must be suspended. Failure to do so could result in serious injury or a facility fire. Additionally, a properly lubricated roller chain is essential to ensure long-term performance.
The surface of the roller is often rusted and scratched. Over time, these little scars can spread to the drive, damaging it. Also, the chain may not be properly spaced and timed. Therefore, it is very important to check regularly to ensure that the chain is in top condition. When the chain wears to 3% or more, the entire roller chain needs to be replaced. Failure to do so may damage the drive, the roller sprocket, or the entire chain.
Given the chain’s processing environment, lubrication is critical to its performance. If the chain is lubricated, it must be re-lubricated frequently. However, lubricated roller chains are susceptible to contamination, especially in the biomass industry. In these environments, airborne organic particles and debris from the biomass industry can contaminate lubricated roller chains. This is why maintenance is important for lubricating roller chains.
Preloading
The benefits of preloading roller chains are well documented. In general, preloading eliminates the initial elongation of the roller chain, increasing its service life. Preloading is an effective way to achieve this, and a preloading chart can help illustrate the benefits of this process. Chains with little or no preload will stretch significantly during drive start, while chains will stretch rapidly as the surface hardness of the wear parts increases. Additionally, a properly preloaded chain has little or no elongation during the initial start-up of the drive, extending wear life.
Premium manufacturers apply the preload concept during their production phase, aligning all major components at the same time. This approach helps eliminate elongation issues that lead to rapid degradation of the roller chain. If this is not checked, the chain drive will stretch immediately over time. To avoid these problems, it is important to purchase a high-quality preloaded roller chain from a reputable source.
The heat treatment process is an effective way to prevent excessive wear of the roller chain. Heat treatment is a complex process that takes place in a factory during manufacturing. This process helps the rollers maintain high hardness and depth, preventing breakage. When buying a roller chain, make sure that the chain is heat treated and that the chain is manufactured to a high degree of precision. It also ensures that the product can be used for a long time.
In addition to performance benefits, preloading can also reduce initial elongation. A preloaded roller chain will exhibit near linear elongation, whereas a non-preloaded chain will experience rapid elongation. Therefore, they will reach the recommended 3% elongation earlier. Make sure the chain is properly lubricated. Also, consider how the chain is arranged. This is critical for optimal longevity.
