#140-3 cottered triple roller chain strictly follows ANSI B29.1 standards with 1-3/4 inch pitch. Fabricated from high-grade alloy steel, all components are precisely heat-treated to enhance tensile strength, wear and fatigue resistance.
The cotter pin structure allows quick disassembly and flexible length modification on site, saving installation time. Triple-strand design greatly boosts load-bearing capacity, perfectly suited for heavy-duty mining conveyors, large industrial transmission equipment and high-torque machinery. Pre-stretching processing restrains chain elongation under long-time heavy loads. It runs smoothly even in tough environments and comes with matching connecting links for easy assembly, delivering reliable long-term service.
