About #140H-2 Heavy Duty Roller Chain
#140H-2 double-strand heavy series roller chain complies with ANSI B29.1 standard with 44.45mm pitch. Different from standard #140-2 chain, it adopts thicker reinforced link plates to boost fatigue resistance and shock load capacity by nearly 15%.
All pins, seamless bushings and solid rollers are made of premium alloy steel with carburizing quenching and shot peening, delivering ultra-high tensile strength and low elongation under heavy impact. Double-row structure doubles load capacity for harsh high-stress scenarios.
Perfect for mining, metallurgy, port heavy conveyors and construction machinery. Standard carbon steel in stock; stainless steel and attachment chains customizable. Matches dedicated #140H duplex sprockets, complete with connecting links for global export.
