Heavy-duty roller chain is a chain specially designed for transmission in high-load environments, which has a stronger load capacity and higher durability to meet the high requirements of mechanical transmission in heavy industry.

P series high-strength short-pitch roller chains through the overall optimal design of structural size, part materials and heat treatment processing, its tensile strength is significantly increased compared with the A-series standard roller chains, usually can be increased by about 28% or more.

It refers to a chain with double or three-chain structure. This chain usually has high strength and wear resistance, suitable for the need to withstand large tension and impact occasions.

A forged chain is a chain manufactured by a forging process that can give the chain higher strength and durability.

The SH series high strength short pitch heavy duty roller chain is a chain product designed for heavy duty and harsh working conditions, with excellent tensile strength, vibration load resistance and compact construction
