#180H-3 heavy-duty triple strand roller chain follows ANSI industrial standards, engineered for extreme load and high-torque transmission scenarios. Reinforced thickened plates, oversized solid rollers and heat-treated pins deliver superior tensile strength and wear resistance, outperforming standard series under continuous heavy operation.
Made of high-strength carbon steel with precise quenching & tempering, it resists deformation, fatigue and abrasion. The triple-strand layout evenly distributes heavy loads, ideal for mining machinery, large conveyors, heavy lifting equipment and industrial transmission systems. Custom surface treatments like black oxide and stainless steel versions are available. Stable running, long service life, low maintenance cost, reliable heavy-load performance for harsh working environments.
