#140-1 single-strand cottered roller chain follows ANSI B29.1 standards with a 44.45mm pitch. Fitted with cotter pins at both pin ends, it allows quick disassembly and convenient on-site length modification for easy maintenance.
Made of high-quality alloy steel, all core parts are carburized quenched and shot-peened to achieve great tensile strength, wear resistance and anti-elongation performance. Seamless bushings and solid rollers reduce friction for smooth, quiet operation under heavy loads.
Suitable for mining, metallurgy and industrial conveying equipment. Carbon steel models are readily available; stainless steel and attachment chains can be customized. It matches standard #140 sprockets and comes with complete cottered connecting links for worldwide shipment.
