chain

Different types of drive chains

There are many different types of drive chains. You should be able to differentiate between roller chains, forged rivetless chains, double chains, flat-top chains, and helical chains by the terms used. This article will provide information on the different types of chains. Then, you can choose the right one according to your needs. If you haven’t purchased a chain yet, read this article to get started. It will also provide information on the pros and cons of each type.

roller chain

There are several differences between drive chains and roller chains, but in essence, the two are functionally similar. The choice of which type to use depends largely on the type of environment it will be exposed to. While roller chains are suitable for clean indoor environments, they are not very forgiving when it comes to rubbing against the rails. Following are the main differences between a drive chain and a roller chain. Using the correct drive chain is essential for a smooth and efficient running machine.
Roller chain drive chains come in many different weights and tensile strengths. For light-duty applications, use a smaller pitch chain. For heavy-duty applications, use larger pitch chains. The design simplicity of these chains makes them ideal for a variety of applications. While they are great for a variety of applications, the durability of these chains makes them ideal for a variety of applications. Some of the main uses of roller chain drive chains are listed below.
When replacing the drive chain, be sure to follow the safety guidelines. The most important thing to remember is not to place the chain on a dirty floor as it may cause stretch or damage. After removing the chain from the sprocket, apply the measured load specified by ANSI to it. If the load exceeds this value, the chain may bend. A suitable load for measuring a drive chain should be at least six links.
While roller chains are usually made of carbon steel, some are made of stainless steel and are used in food processing machinery. In these environments, the chain may be made of stainless steel for lubrication. Brass and nylon are also sometimes used to meet these requirements. Regardless of the application, however, choosing the right drive chain is critical to the success of a roller chain machine. It is important to maintain the proper balance between the roller chain and the machine.
To properly use a roller chain, first determine the size of the sprocket used for the drive. The size of the chain should be smaller than the smallest sprocket to prevent tooth interference and provide adequate winding on the smaller sprocket. A good practice is to choose a drive chain with a center distance of 30 to 50 times the chain pitch. The longest possible center-to-center distance is approximately 80 times the chain pitch but is not recommended for high-speed applications.

Drop forged rivetless chain

Drop-forged rivetless drive chains are made of drop-forged steel components. Their proportions are suitable for strength and lightweight. Forged rivetless chains are generally divided into three types. Each of these types has its own set of important specifications. Key topics include minimum ultimate tensile strength, chain length tolerances, and link dimensions. Read on to learn more about each type and its uses.
One of the main features of forged rivetless chains is that, despite their relatively low price, they are designed to be very durable. The quality of a forged chain depends on the structure and design of the chain. The manufacturer of this type of drive chain is CZPT, which has a large stock of these chains. The chain is proof tested after assembly and comes with a two-year parts replacement warranty.
Forged rivetless chains are available in a variety of pitch sizes and strength grades. They are made of cast manganese or alloy steel and have an average strength of 24,000 to 300,000 pounds. These chains are suitable for automotive, conveyor, and material handling as well as meat packaging, sugar processing, and steel mill applications. They are also widely used in conveying systems. To ensure quality and performance, manufacturers offer a variety of forged chains.
CZPT offers forged CZPT drive chains for fatigue-free operation. The chain includes a solid one-piece forged drive pawl for optimum durability. Chains are available in Figure 8 and in D-shape styles. For more information, please contact CZPT directly. Custom Drop-Forged rivetless drive chains can be ordered. Manufacturers also offer custom chains for specific application needs.

double chain

Duplex drive chains have two sets of rollers instead of one, producing twice the power. Double chain roller chains have pins and roller bearings, while triple chain chains have an extra row of plates to accommodate the three sprockets. They are usually interchangeable with each other. They are available for US, UK, and ISO standards. They are made of carbon steel, stainless steel, and nickel or nickel-plated.
chain

flat top chain

Flat-top drive chains are ideal for curved or straight tracks and come in many different types and thicknesses. These chains are highly resistant to wear and are usually made of steel, stainless steel, or plastic. CZPT manufactures special brands of flat-top chains with high wear resistance and excellent noise reduction. In addition to being versatile, flat-top chains can be used in a variety of industrial applications.
There are two main types of CZPT chains: solid top or raised rib. One piece is formed from a single unit link and the other has roller base links for added strength. The two-piece chain combines flat tabletop links and a roller bottom chain for added strength. These chains are available in widths up to 20 feet and are available in a variety of widths. These chains are available in stainless steel, cast iron, or plastic.
The hinge pin is another important part of the flat top chain system. Support chain plate to ensure smooth conveying. The hinges are available in single hinge pin and double hinge pin styles. Standard hinge pins are designed for straight, narrow-width chainplates; double hinge pins are designed for longer, heavier products. The hinge pins also come in many different materials, including aluminum and galvanized steel. This allows for customization based on machine design, operating conditions, and drive method.
Whether your flat-top chain conveyor system is large or small, a high-quality flat-top chain will get the job done. With their low maintenance and low maintenance design, these chains are easy to clean and maintain. They can accommodate workpiece pallets of various sizes, and their flexibility makes them ideal for many different applications. They can also be highly customized for various industries. So if you need an industry-specific conveyor, then a flat-top drive chain is the way to go.

buy drive chain

Buying a drive chain requires a certain understading of its characteristics. This article discusses the different types of chains available, including Silent, Flat-top, and Duplex. By the end of this article, you should have a basic understanding of what each type of chain is for. First, here are some basic rules to keep in mind when shopping for a chain. To find the drive chain that best suits your needs, read on.

roller chain

Choosing the right roller chain for your drive chain depends on several factors. First, you have to determine the motor horsepower and rpm for the small drive sprocket. These values ​​determine the size of the chain and the number of teeth on the drive sprocket. Next, you need to determine the size of the conveyor chain, it can be the horizontal, vertical, or curved radius. Depending on your specific needs, you can also choose between two-strand or three-strand chains.
The roller chain of the drive chain must be properly tensioned. It should also have a proper lubrication system. Chain sag should not exceed two to four percent of the center distance (the distance between the two axles). Also, it shouldn’t make any unusual noises or obvious problems. One of the main reasons for excessive wear is the size of the load. Each chain has a specified maximum working load.
The maximum roller chain load must be less than 1/9 or 6 times the tensile strength of the drive chain. This amount should not exceed this threshold, as exceeding this level will result in chain plate fatigue. To avoid this, you should use a roller chain with a higher number of strands. Also, for high power requirements, a roller chain with a higher number of strands is recommended. One final tip for choosing a drive chain: it should not be used when there is a high risk of corrosion or rusting.
The materials used to manufacture roller chains vary according to the specific application. Common materials include steel and stainless steel. However, stainless steel is used in food processing machinery and other environments that require lubrication. Brass and nylon are also sometimes used. These factors determine the selection of suitable materials for the drive chain. If you are not sure which material to use, you can consult an industry professional. These professionals will help you choose the right chain for the job at hand.

mute chain

The design of the silent transmission chain is as follows: the large chain plates 2 are stacked one on top of the other in the direction of the chain length. The connecting rods are connected by connecting pins 3. The outermost and central guide plates 4 are fastened to the connecting pins 3 by means of rivets. This construction helps minimize friction on the sliding surfaces of the chain. Chainplate 2 of the silent transmission chain is usually made of stainless steel.
The link plates are made of steel and have a rectangular shape with pinholes 41. These guide plates have no teeth but have curved surfaces that guide the silent drive chain on the sprockets. In addition, the rear portion of the guide plate is higher than the portion of the chainplate. This feature improves pitch balance. The present invention is also applicable to silent transmission chains using rockers.
When it comes to chain design, it’s important to remember that silent drive chains are often used in automotive engines, especially timing and cam drives. This type of drive reduces noise and vibration due to its low engagement angle and links engagement with the sprocket. However, these applications are not limited to timing and cam drives; they can also be used for front-wheel power transmission. For example, silent drive chains are designed to resemble those used in NASCAR racing engines.
The design of the silent drive chain is based on the structure of the roller chain. Its components are standardized and manufactured according to pitch. There are single-row and multi-row versions. Quiet chains, also known as inverted tooth chains, are shaped to reduce noise from stretching. It’s also designed to minimize the amount of friction caused by small changes in pitch. Its teeth don’t slide against each other, so the chain is smoother and more durable.

flat top chain

One of the important parts of the flat top chainplate system is the hinge pin, which is used to fix the chainplate and is responsible for the smooth and efficient conveying of the chainplate. There are several types of hinge pins, including single hinge pins and double hinge pins. The single hinge pin is suitable for the chainplate with a small span and small bearing capacity, and the double hinge pin is suitable for the chainplate with a large span and high bearing capacity.
The side bending flat top chain is suitable for conveying large and medium workpiece pallets. They can be made of steel or plastic, each with its own advantages. Both chainplates are designed to convey material smoothly. Side curved flat-top chains can be used on straight conveyors. They have a low coefficient of friction and can transport weights up to 1.2 kg/cm. They can also be combined with HD profiles.
Flat top drive chains are usually made of plastic material and come in two types: tabletop chains and buffer chains. They come in a variety of widths, but the most popular are standard widths, ranging from 3.25 inches to 12 inches. MatTop chains are usually shipped in 10-foot lengths. They come in different styles, but they all have the same basic specs. Tabletop chains are designed for general conveying, while pad chains are used for specific applications. Solid top chains are suitable for conveying bulk materials, while wide pad chains can handle large volumes of fluids and/or solid-solid mixtures.
These chain conveyors can be used to convey, connect or lift small items. This type of chain is especially useful in industries where the product is hot or greasy. The modular design of these chains allows them to be configured in three dimensions, making them suitable for production changes and transitions. They also help reduce slack in the chain. Flat top chains are commonly used in final assembly and mechanical or paint restoration in the automotive industry.

double chain

Besides the roller chain, another type of chain drive is the double drive chain. This type of chain consists of a series of short cylindrical rollers connected together by side links and driven by gears called sprockets. This type of chain is very reliable and only requires a tractor with a high rpm PTO. It is manufactured by CZPT and is available in many different sizes and finishes.

Self-lubricating chain

Self-lubricating drive chains are the ideal solution for applications that do not require the relubrication of conventional chains. This maintenance-free roller chain features fully heat-treated components that increase the chain’s fatigue resistance and strength. It’s sintered alloy bushings are oil-impregnated, reducing the chance of premature wear and elongation. Its self-lubricating properties enhance its durability and work well even in hard-to-reach places.
CZPT self-lubricating roller chains feature preloaded sintered steel bearing pins and oil-impregnated sintered bushings. These chains are drop-in replacements for standard roller chains and run on the same sprockets as standard chains. In addition to being maintenance-free, self-lubricating roller chains are compatible with most existing sprockets and are ideal for demanding applications.
The O-ring chain concept was used to develop self-lubricating systems. It has two or more annular grease storage chambers. A self-lubricating bushing roller chain has an oil reservoir between its pin chain and the roller chainplate. A grease seal between these two plates isolates the moving parts and keeps the joints well lubricated. O-rings are made of special nitrile rubber, whose properties vary by application.
CZPT SLR conveyor chains and CZPT SLR drive chains have rollers on sintered bushings. CZPT SLR chains and SLR conveyor chains are self-lubricating and have a higher working load than standard ANSI chains. They may not be interchangeable with other self-lubricating chains from other manufacturers. Self-lubricating drive chains are the best solution for demanding industrial applications requiring heavy-duty, reliable conveying.

How to choose a roller chain for a conveyor

When choosing a roller chain for your conveyor, the easiest way is to refer to the horsepower and RPM charts. The horsepower and rpm of the small drive sprocket will determine the size and number of teeth of the chain. Conveyor chains are available in a variety of options, including moving products horizontally, vertically, or around a bend radius. When choosing a conveyor chain, consider the purpose of the chain. For example, if you’re delivering products to customers’ doorsteps, you might choose chains that can move products up and down a hallway or warehouse.

Double pitch

Double pitch roller chains are a popular way to drive agricultural equipment. It has twice the pitch of a standard roller chain and is ideal for light-duty drives. Extended pitch increases performance at lower speeds, but requires fewer components per foot than standard single-pitch chains. Compared to single-pitch roller chains, double-pitch chainplates are longer and are suitable for lighter loads. Read on to learn more about double pitch chains and how they can improve your operation.
The most common type of conveyor chain is double pitch. It is used in the auto parts industry, as well as in the precision machinery industry. It is made from the same components as the standard drive roller chain, except it has longer side plates. Double pitch chains are often used on slow-moving conveyors to reduce the stress placed on them. Industries that commonly use double pitch conveyor chains include airport equipment manufacturers, lumber mills, and fruit packing plants.
RS series roller chains are manufactured from high-quality stainless steel. It has excellent chemical and abrasion resistance and is available in a variety of cord lengths. RS sprockets have over 30 teeth. They contain all the necessary connection links for easy installation. PEER Chain offers double pitch roller chain attachments including pre-stretched chains, sprockets, and other attachments.
Double pitch roller chains have several advantages over standard chains. Double pitch chains have double the pitch, making them ideal for conveying applications such as conveyors. In addition to that, it also provides ANSI-compliant styles. These chains also have free connection links. When shopping for a double pitch roller chain, be sure to choose the one that fits your requirements and budget. They will last longer and save you money in the long run.
Double pitch roller chains to ANSI standards feature oversized rollers. These chains are best suited for applications where the product is mounted on top of the chain. They are ideal for agricultural applications where cotton is on top of the drum. Also, this type of chain is used in light-duty conveyors and agricultural applications. You can find double pitch roller chains in a variety of sizes and styles. And, as long as you know what you want, you’ll be happy with the results.

Self-lubricating

Self-lubricating roller chains eliminate the need for manual relubrication, providing long-lasting operation and reducing maintenance costs. These chains are particularly popular in industries such as the food and beverage industry, textiles, printing, and sawmills. They can also replace standard roller chain drives and conveyor chains. Manufactured to the specific standard ISO R606, these chains are ideal replacements for conventional chains. PC chains are particularly beneficial for food and beverage production and packaging applications due to their anti-corrosion properties.
Self-lubricating roller chains meet ISO, ASME/ANSI, and DIN standards. They are interchangeable with standard chains of the same size and shape and can be used in a variety of industrial applications. Self-lubricating chains have special oil-impregnated sleeves to reduce maintenance time. These chains are also suitable for applications where cleanliness is an issue.
Self-lubricating roller chains are manufactured with unique RS attachments. Rather than a traditional roller chain with an external lubricating ring, this type of chain retains the lubricant within its bushings. During operation, the application generates heat, heating the lubricant, which flows out of the pin and bushing area. Therefore, CZPT roller chains are ideal for certain food conveying applications.
In addition to self-lubricating roller chains, carbon steel, stainless steel or nickel-plated steel are also available. Self-lubricating roller chains are available in different sizes depending on the application, including 0.375″ wide profile straight-chain, extended pin chain, and four-link. In addition, these chains are also available in ANSI and BS chain specifications.

Accumulation

Whether you need to move large or small loads, accumulating roller chains are a viable solution. This chain conveyor is designed with low back pressure to transport large and bulky items with minimal noise. Free-running rollers within the chain help create a smooth build-up surface. These chains are available in a variety of options, including accumulating rollers of different pitches.
The accumulation and release roller chain 14 includes an upper part 15 and a lower part 16. The upper part 15 rests in the upper subspace 28, while the lower part 16 rests on the top side 20 of the profile. As the upper belt 15 rolls around the accumulation roller chain 14, it aligns with the lower chain 16 to form a continuous receiving space. This arrangement allows the accumulation roller chain 14 to rest on the top surface of the support profile 11.
A cumulative roller chain consists of many individual parts. Each section of the chain has an elongated cylindrical shape and is connected to each other by hinged joints. Each chain section also has an accumulation and release roller associated therewith. Each roller protrudes from the upper side 20 and the lower side 21 of the chain portion. The accumulation rollers are movable about an axis 22 extending transversely to the longitudinal axis of the chain.
A feature of the stacking and releasing roller chain is its simplicity. The conveyor has a profiled section that is permanently divided into two cross-sectional spaces. The bottom space is closed from all sides. The upper space accommodates the conveyor line. The contoured portion includes an opening that guides the bottom strap. A shunt can also be inserted between the two sections. The accumulating roller chain system is a convenient and versatile way to move bulky items.
There are many different types of accumulating roller chains. Some chains have offset rollers for optimal load distribution. Others have protection to prevent machine wear. Some run without lubricant, which is a safety advantage. In addition to protection, cumulative chains can also provide protection. The side bow version of the accumulation and release roller chain with offset accumulation and release rollers is designed for conveyor systems with very small bend radii.
chain

Without bushing

Bushless roller chains are the most common type of industrial chain. They are simple in design and require only regular maintenance. Regular maintenance includes lubricating, assessing wear, and replacing worn sprockets. For more information, please read the following information:
The outer chainplates and the inner chain plates are alternately arranged in pairs. The connecting pin extends through the hole in the inner link plate. The rollers thus positioned can be rotated on the connecting pins. Oil provided between the outer circumferential surfaces of each connecting pin serves to lubricate the chain. This system reduces noise and wears caused by collisions between inner chain plates and sprockets.
Compared to traditional roller chains, bushings roller chains have rollers around the bushing. These rollers are in rolling contact with the sprocket teeth, providing low friction and excellent wear resistance. To ensure smooth operation, bushings roller chains must be greased to prevent rust and keep the chain properly tensioned. Lubricated chains run smoother and last longer.
In a bushingless chain, the inner links are shaped like half bushings and ride on the rollers. The pins go through the outer plate and connect the inner links to the rollers. The outer plates overlap the inner links and open the pins. This system is also known as a heterochain. This type of chain is more common than traditional roller chains. If you are not sure which type of bushingless roller chain to choose, you may need to purchase an additional pair of inner chainplates.
Linerless roller chains may also include chain guides. In a bushingless roller chain, the outer and inner link plates conform to the surfaces of the guide rails. Thus, the large area of contact between the chain and the guide rail is eliminated, the friction loss is reduced, and the power transmission efficiency is improved. These properties make bushless roller chains more efficient and durable than traditional roller chains. It’s also less noisy. If you are looking for a chain with a lower noise level, a bushingless roller chain may be the right choice for you.

Types of Roller Chains

There are several types of roller chains available. These chains have different properties and serve different purposes. Here you will learn about diamond roller chains, X-ring and O-ring chains, inverted tooth chains, and self-lubricating chains. You can choose the type that best suits your needs by reading this article. It will also help you make an informed decision. Buying the right roller chain for your needs is easy. Hope this article is helpful to you!

Diamond roller chain

Diamond roller chains are more efficient than other chains and can significantly extend chain life. The superior design of the chain prevents internal rust from seeping out. Additionally, Diamond ACE features a corrosion-resistant exterior and a zinc-nickel pre-assembled coating that provides extended corrosion protection and wear resistance. These features reduce chain downtime and labor costs, saving a building materials manufacturing company nearly $33,000 over the life of its machines.
Diamond series chains lead the industry in quality and durability, with industry-leading tensile strength and the lowest total cost of ownership. With a diverse product portfolio including standard chains, specialty chains, and custom chains, the company is sure to provide the right chain for your application. The company also offers a wide range of accessories for a variety of machinery. For more information, please visit the company website.
As one of the leading manufacturers of roller chains, the CZPT Company offers unparalleled expertise and wear resistance in the power transmission market. CZPT is trusted by leading industries and provides the highest return on investment. The diamond is a symbol of strength and durability, and the company chose it as the company’s trademark to convey its core values. CZPTs can last up to 100 years or more in harsh conditions, even in underwater environments.

Self-lubricating chain

Self-lubricating roller chains are designed to increase performance while maintaining a high level of cleanliness. These chains are made of sintered alloy bushings impregnated with lubricant and pins specially treated to release oil when necessary. These chains have a long service life and are suitable for environments where regular lubrication is difficult. Below are the benefits of self-lubricating roller chains.
Maintenance-free self-lubricating roller chains are the perfect replacement for standard roller chains. They are suitable for packaging, printing, textile, and sawmill applications. These chains reduce downtime and increase productivity. Furthermore, they reduce the risk of contamination. Another advantage is that there are many types of self-lubricating roller chains to choose from, allowing you to choose the one that best suits your needs. To learn more about these benefits, read the Maintenance Free Roller Chains Market Report published by Dataintelo.
CAN-AM self-lubricating roller chains ensure stick-free operation. These chains are available in ANSI/BS standard and double pitch variants. They feature oil-impregnated bushings and preloaded sintered steel bushings for long life. These self-lubricating roller chains are drop-in replacements for standard roller chains and run on standard roller chain sprockets.<br/

X-Ring and O-Ring Chains

Both O-ring and X-ring roller chains are sealed and unsealed. You’ll find them on vintage bikes and small economy cars. Other applications include bulldozer treads and conveyor belts. Standard chains are made of simple plain bearings that require lubrication every few hundred miles. While the former is the most affordable type of roller chain, they do require more maintenance than O-rings.
The main difference between the two types of chains is the friction and cost they generate. X-rings are slightly less expensive, but they create less friction than O-rings. X-rings are a more affordable option for road riders, while O-ring chains are more expensive for off-road racers. In some cases, X-ring and O-ring roller chains can be distinguished by the price tag alone.
Both X-ring and O-ring roller sprockets are available in a variety of styles. The two styles offer comparable performance, but there are some key differences to consider. X-rings are generally better for longer travel as they offer greater durability and performance. O-rings are usually more expensive than X-ring chains, but if you’re thinking about long trips, they’re a great option.

Reverse chain

Inverted roller chains are often referred to as silent chains. They have two protrusions on each board. The outer surface is ground to include an angle of sixty or seventy degrees. These protrusions about the working surfaces of the sprocket teeth. The inner surface or shape of the sprocket can clear the sprocket. This produces a silent but still valid chain. This type of chain is used in transmissions to move heavy objects.
There are three basic types of inverted toothed roller chains. Simple chains are single chains, while double and triple chains have two or three strands. In these types of chains, the pins pass through-hardened steel bushings at the ends of the links. The main difference between these types is their size. If you are not sure what size you need, first calculate the capacity of the chain. You might be surprised to learn that the smaller the diameter the better.
The number of links in a reverse roller chain determines the frequency of vibration. The frequency depends on the size of the chain and the length of the chain between the sprockets. The shorter the chain, the bigger the “pull” – the up-and-down jitter caused by the sprocket. This causes additional peak loads on the drive and shortens its life.

PEER Chain’s Heavy Duty Series Double-Stranded Roller Chains

Heavy-duty double-strand roller chains are ideal for industrial and agricultural use as they provide extra stability and strength. PEER Chains manufactures chains in various lengths and pitches and offers different accessories including sprockets and pre tensioned chains. These chains are also available in a variety of different alloys and grades. Listed below are some of the most common uses for heavy-duty double strand roller chains.
Heavy-duty PEER double-strand roller chains are available in a variety of styles and types, including the HKK NICKEL PLATED series. These chains are best suited for outdoor and mildly corrosive applications. They use a patented process to increase fatigue strength and reduce initial elongation. In addition, HKK double pitch twin-strand roller chains are lighter and less expensive than standard roller chains.

Maintenance of Mechanical Flexible Couplings

Proper maintenance of mechanical flexible couplings on roller chains is critical to ensuring the proper operation and reliability of the system. Maintenance of these couplings includes periodic inspection of the components. Check for signs of fatigue and wear. Regular inspections will help determine when to replace the coupling. It also helps determine the remaining life of the coupling.
Couplings should be replaced periodically for optimum performance. When replacing, be sure to use the correct parts. Make sure the coupling type matches the coupling type and chain size. Identical coupling parts may not fit, so a cross-reference guide or manufacturer’s spec number may be helpful. Make sure that the coupling is fitted with a suitable roller chain.
Mechanical elastic couplings on the roller chain can be easily lubricated to avoid premature failure. Elastomeric couplings can accommodate minor shaft misalignments and are suitable for high rotational speeds. Also, it absorbs shocks. Its flexibility is due to loose components. Additionally, lubrication is essential to reduce wear on coupling components.

Roller chain size

Knowing the basic dimensions of the rollers is essential if you need to find the right roller chain for your needs. The three key dimensions of a roller chain are pitch, width, and pin diameter. These dimensions are important because they are used to identify the type of chain. These dimensions do not normally appear in chain manufacturer catalogs. They are usually designed for people designing new equipment. They are not important to maintenance technicians, but they are important to know if you are looking for a specific type of roller chain.
Once you know the exact size of the chain, you can move on to choosing the correct type. You can use the printable template to measure your chain, which makes it easy to compare with the size chart. Don’t forget to check the rest of the roller chain’s specs to make sure it fits your machine. Using the Roller Chain Size Chart is an easy way to determine the proper length, width, and height for your application.
When buying a roller chain, be sure to check the number of teeth and the ratio of the two. A common ratio is 2:1. The drive sprocket must have at least twice as many teeth as the roller sprocket. If the chain is used for high precision, check the type of sprocket as this will determine the correct size of the chain. You can also choose between slip-fit ​​and press-fit mid plates.
