ANSI #50-3 triple-strand cottered roller chain strictly follows ANSI industrial standards. Built with high-carbon steel components, it undergoes precision heat treatment to boost hardness, wear resistance and tensile strength for stable heavy-load transmission.
Cottered pin design enables easy disassembly, maintenance and length adjustment, ideal for frequent servicing scenarios. Three parallel strands deliver larger load capacity than single/double chains, fitting agricultural machinery, conveyors, packaging equipment and general power transmission systems.
Fine surface finishing resists abrasion and moderate corrosion. Uniform dimensional accuracy ensures smooth meshing with matched sprockets, lowering vibration and operational noise for long service life.
