#140-2 duplex cottered roller chain complies with ANSI B29.1 standards with a 1-3/4" pitch. Constructed from premium alloy steel, every part receives strict heat treatment for outstanding tensile strength and wear resistance.
Equipped with cotter pin style links, the chain allows convenient disassembly and on-site length adjustment without special tools. The double-row design offers superior load capacity, ideal for heavy-torque equipment such as mining conveyors and industrial transmission machines. Pre-stretched during production effectively reduces elongation under continuous heavy loads. Smooth operation and long service life guarantee stable performance in harsh working conditions. Matched connecting links are supplied together for easy installation.
