What is the pitch on a roller chain?

The pitch of a roller chain is the distance between adjacent roller pins or rivets. Chains can have different pitch ranges depending on their size and application. A pitch of 0.250 inches indicates a light chain, while a pitch of 3.0000 inches indicates a heavy chain. The ANSI standard measures the chain pitch from the center of one roll pin to the center of the next link.
Another key metric for roller chains is tensile strength, which represents the maximum load the chain can withstand before breaking. While tensile strength is the most important characteristic of a roller chain, fatigue strength is equally important. The fatigue strength of a chain shows how durable it is. Fatigue strength indicates the load capacity of a roller chain over an extended period of time.
