Roller chains are commonly found in a wide variety of power transmission, agricultural, and industrial applications. This popular type of chain provides a reliable mechanism for transmitting power to many kinds of different moving parts. Since its invention in 1880, conveyor, automotive, food and beverage, and farming equipment have boasted these popular and common types of chains to keep them running. This roller chain size chart will help you find the ideal size of roller chain for your replacement or OEM needs.
How To Measure Roller Chain
Whether you're building something from scratch or making an update to an existing project, finding the right size for your roller chain is a critical first decision. In order to accurately measure roller chain, you'll need to know the overall width, diameter and width of the roller, plate thickness and height.
Single Strand Roller Chain Size Chart
Like all of our roller chains, our single strand roller chains are hot-dipped to ensure 100% lubrication of the components and heat-treated for wear resistance. Our hot dipped lubrication method ensures that each single strand roller chain performs at maximum capacity and that wear life is as long as possible. PEER Chain experts are proud to offer highly durable single strand roller chains for your convenience. Each of our single strand roller chains are pre-loaded over the course of manufacturing, which effectively minimizes initial elongation once you receive your product. You will find our single strand roller chains used in a variety of places such as the food industry or as conveyors. At PEER Chain, we understand that down time can mean losing business and profits. Our single strand roller chain is the missing link that your company needs to keep machinery and day-to-day operations running smoothly.

Functions of Roller Chains
In general, roller chains have four key functions:
- To move materials or objects from one location to another
- To transmit power
- To ensure that an action occurs consistently after the previous action over a period of time; i.e. synchronization
- To shift the direction of motion from linear to rotary
Roller chains have significant advantages over belt drives for these functions, as they have very little slippage or stretching across the chains even with a heavy load and are incredibly efficient and long-wearing. Our roller chains offer exceptional strength and durability, thanks to our effective heat treatments and 100% lubrication techniques. Roller chains are exceptional for use in a high-stress environment as they will hold up under even the most difficult conditions such as high and low temperature, or start-stop action usage. Regardless of industry, roller chains are necessary to keep operations running smoothly in various light and heavy-duty applications. By investing in quality roller chains for your day-to-day machinery, you are more likely to enjoy consistent and steady business. These roller chains also have a virtually unlimited shelf life as long as they are stored and maintained in the proper environment.
Sizes of Roller Chains
As you can see above in the roller chain size charts, there is a wide range of sizes that are available in this versatile chain. Single and multiple-strand roller chains are available, with different weight and tensile strength ratings based on the manufacturing requirements for their particular use. Since chains are used as a drive and as part of a conveyor system, the range of sizes can be quite significant. Smaller pitch chains are often found in light to moderate load applications while larger pitch chains are used in heavier load applications.
Roller chain sizes are standardized according to ANSI/ASME or ISO British standards, which are meant to provide interchangeability of design and dimensions for chains, sprockets, and attachments. Fortunately, you will find a wide range of options available at PEERChain.com. Before purchasing your very own roller chain, it is crucial to determine which size component will best suit your operational needs. If you aren’t sure which roller chain will work best for your applications, simply connect with one of our friendly experts.
Roller chain specification includes key values for:
- Size
- Pitch
- Roller Width and Diameter
- Average Ultimate Tensile Strength
- Sizes for ANSI/ASME standard roller chains range from 25 to 240.
Tensile and Fatigue Strength of Roller Chain
Tensile strength is one of the key measurements of roller chains and indicates specifically the one-time load capacity of a chain before it breaks. It is important to note how tensile strength is different from fatigue strength, as both are used to indicate the overall durability of a particular chain. Fatigue strength is defined as the load at which the roller chain will likely begin to fail after continuous use over a period of time. Therefore, the main distinction between tensile strength and fatigue strength has to do with whether one-time load capacity or load capacity over an extended period of time is being measured.
