About #140H-3 Cottered Roller Chain

#140H-3 is triple-strand heavy-duty cottered roller chain complying with ANSI B29.1. The “H” stands for thicker side plates to boost tensile strength and shock resistance. It adopts cotter pin structure instead of rivets, easy for installation, disassembly and on-site maintenance.

Made of heat-treated carbon steel with shot-peened link plates, this chain delivers excellent wear resistance and fatigue performance. Pitch is 1.75 inch (44.45mm). Widely applied in heavy-load industrial transmission like mining, port machinery and large conveyors. Interchangeable with standard ANSI sprockets.
