About #140-3 Triple Roller Chain

#140-3 triplex roller chain fully complies with ANSI B29.1 standard with 44.45mm pitch. Its three-row parallel structure delivers nearly triple load capacity compared to simplex #140 chain for ultra-heavy power transmission.

Made of premium alloy steel, all pins, bushings and solid rollers undergo carburizing quenching and shot peening, featuring high tensile strength, outstanding fatigue and wear resistance. Seamless bushings cut friction for smooth, low-noise operation under extreme impact loads.

Ideal for mining, metallurgy, large port conveyors and heavy construction machinery. Standard carbon steel in stock; stainless steel, heavy H-type and attachment chains are customizable. Matches standard #140 triple sprockets, complete with connecting links and packed for global export.
