Heavy duty series roller chains are manufactured to ANSI B29.1 Standards but feature thicker side plates. Heavy-duty roller chains are optimal to use in agricultural applications, skid steers, heavy equipment, and any application that you are looking to increase the strength of the chain without having to go up a size. 

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

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

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.

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