Heavy duty series Cottered type roller chains 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.

At YQ-CHINATRANSMISSIONS, we are proud to offer the highest quality Heavy duty series Cottered type roller chains to our customers. 

Having thicker side plates not only drastically increases the strength and fatigue resistance of a roller chain, but it also reduces stretching and wear that happens over time.

Teeth hardened, stamping, surface treatments as customer's request.

All stock short pitch chains go through high quality control to suit your requirement.
