About #80H-3 Cottered Roller Chain
#80H-3 cottered roller chain is ANSI B29.1 standard heavy-duty triple strand roller chain. Thick heat-treated side plates greatly improve tensile strength and impact resistance. The cottered pin design allows convenient disassembly and field maintenance.
Fabricated from premium carbon steel, precision machined solid rollers and bushings deliver outstanding wear performance. It matches standard #80 sprockets, widely applied in heavy-duty conveyors, mining and agricultural machinery. Custom lengths and surface treatments are available upon request.
