#80-3 triple-strand roller chain conforms to ANSI standard sizes. Produced from premium carbon steel with standardized heat treatment, it features high ultimate tensile strength, great wear resistance and reliable anti-fatigue property for heavy-load transmission demands.
Precision processed pins, bushings and rollers enable smooth meshing, low friction and quiet running performance. It is widely used in heavy-duty conveyors, construction machinery, agricultural equipment and large industrial drive systems. Optional black oxide or galvanized surface treatments are available to strengthen rust protection. Every chain undergoes strict quality inspection to restrain elongation and maintain stable long-term operation under sustained heavy working loads.
