About #80H-2 Cottered Roller Chain
#80H-2 cottered roller chain is ANSI B29.1 standard heavy-duty double strand roller chain. It adopts thicker heat-treated side plates to boost tensile strength and shock resistance. The cottered pin design enables easy disassembly and on-site maintenance without cutting pins.
Made of high-quality carbon steel with precision machining, solid bushings and rollers offer excellent wear resistance. It fits standard #80 sprockets, widely used for agricultural machinery, mining and heavy transmission equipment. Custom lengths and surface treatments are available.
