About #40-4 Multiple Roller Chain
ANSI #40-4 is a 4-strand standard roller chain compliant with ANSI industry specs. Built with high-carbon steel components, it delivers superior tensile strength and stable load capacity for heavy-duty transmission tasks.
Precision machined pins, solid rollers and heat-treated link plates ensure low friction, long service life and strong wear resistance. The multi-strand design evenly distributes heavy loads, ideal for mining, agricultural machinery, conveyors and industrial drive systems.
Strict dimensional consistency enables seamless sprocket matching. Our chains undergo rigorous quality inspection to guarantee reliable performance under continuous high-load operation. Compact structure, easy installation and maintenance.
