Nitro 81X roller chain is built to withstand harsh conditions where many other brands will not hold up. Our 81X chain is built with solid rollers and solid bushings that offers enhanced wear resistance resulting in longer running chain. Another improved feature is the high-strength structural grade alloy pins that are quad staked for increased strength while handling higher loads. The combined features boosts our max working load limits to 4,040 lbs.
