Roller Chains

Double Pitch 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).

Double pitch roller chains are often used in conveyors and agricultural applications, where the moderate-duty links can manage light loads. Their figure-8 style link plates and double the normal pitch mean that these roller chains are cost-effective and durable. The increased pitch reduces the amount of hardware utilized in these chains, reducing the overall cost compared to traditional chains.
