Roller Chains

Roller chains are articulated steel drives made from inner and outer plates, pins, bushes and freely turning rollers. The rollers engage sprocket teeth to transmit positive rotary motion without belt slip, supporting industrial conveyors and machinery where robust, serviceable power transfer is needed.

Questions about roller chains

What should I send to identify roller chains?

Send chain standard and size, strand count, length or link count, connecting link style, material or coating. Measure pitch across several pins on a worn chain, plus roller diameter and inner width, then confirm the standard series. A clear photograph, drawing or readable reference can resolve details that dimensions alone do not show.

How should I select roller chains?

Match pitch, width, strand count, material and lubrication to load, speed, environment, sprockets and duty cycle. Confirm the mating parts and operating environment before ordering, since an apparently similar size can use a different profile, material or internal arrangement.
