About #140-2 Roller Chain

#140-2 double strand roller chain fully complies with ANSI B29.1 standard, featuring 44.45mm pitch and double-row structure for doubled load capacity versus simplex #140 chain.

Crafted from premium alloy steel, all pins, bushings and rollers undergo precise carburizing quenching and shot peening, delivering outstanding tensile strength, anti-fatigue and wear resistance. Seamless bushings and solid rollers lower friction for stable, low-noise heavy-load operation.

Perfect for mining, metallurgy, port equipment and large conveyors. Carbon steel versions are readily stocked; stainless steel, heavy H-type and attachment chains are customizable. Matches standard #140 duplex sprockets, supplied with full connecting links and packed in export rolls. Durable, cost-efficient heavy transmission solution.
