Roller Chains

Standard Roller Chain

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.

A roller chain strand can be shortened by removing links and lengthened by adding whole or a half links (offset links).
