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.
Choose the Right 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. 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.
Matching Single Strand Roller Chain Sprockets
There are six different standard styles of sprockets for single strand roller chain. We stock a complete line of each type! Our standard single strand roller chain sprockets are manufactured with hardened teeth (for tooth counts under 30), used premium quality SAE 1045 steel material, and are finished with black-oxide for corrosion resistance.
