#80-2 cottered roller chain is ANSI B29.1 standard double-strand transmission chain with 1-inch pitch, adopting cotter pin structure instead of riveted pins for easy disassembly, length trimming and on-site maintenance.
All plates, pins, rollers and bushings are precision heat-treated for outstanding tensile strength, wear resistance and fatigue resistance, delivering larger load capacity than single-strand chains. Its solid rollers ensure smooth meshing with matched sprockets, stable operation and extended service life.
Widely applied in agricultural machinery, conveyor equipment, packaging lines and general industrial power transmission systems. Custom cutting length, matched connecting links and offset links are available for flexible installation.
