CA550 Standard single-strand roller chain, standardized by ASME, is an assembly of alternating pin links and roller links. The distance between pin centers is called the pitch. The pitch is what categorizes the size of the chain. The larger the pitch, the higher the load rating. Chains with small pitches carry smaller loads, operate more quietly, and at higher speeds. Multi-strand, small-pitch roller chains are a good solution for high-load, high-speed applications.EPG will always adhere to it enterprise spirit of being practical, innovative, efficient and excellent to make the top international transmission drive.Our capabilities go far beyond the scope of our catalog.
