About #120H-2 Heavy Duty Roller Chain
#120H-2 double-strand heavy duty roller chain complies with ANSI B29.1 standard. It adopts thicker link plates than standard #120-2 chain, with all pins, bushings and rollers precision heat-treated for higher tensile strength, anti-fatigue and shock resistance. Solid bushing & roller structure effectively restrain chain elongation and deliver excellent wear resistance under heavy torque and frequent impact loads.
Designed for high-load industrial transmission, it suits mining equipment, construction machinery, heavy conveyors and large agricultural drives. Available in riveted or cottered end styles. Strict production inspection ensures stable operation, extended service life and lower maintenance cost for harsh working conditions.
