#120H-3 triple-strand heavy duty roller chain conforms to ANSI B29.1 standards. Equipped with thicker side plates than ordinary #120-3 chain, all pins, bushings and rollers are professionally heat-treated for enhanced tensile strength, fatigue resistance and impact resistance. The solid roller and bushing structure minimizes chain stretching and offers outstanding wear resistance under continuous heavy loads and frequent shocks.
It is engineered for high-torque, high-load transmission scenarios such as heavy conveyors, mining machinery, construction equipment and large agricultural transmission systems. Riveted and cottered connection ends are both available. Rigorous quality testing ensures stable running, long service life and reduced maintenance costs in tough industrial environments.
