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 and an average tensile strength of 28,900 lbs.
This 81X chain is also available in 81XH heavy duty and 81XHH super heavy duty for high demanding drives that have extreme & repetitive shock loads.
Large volume and 81X attachment roller chain can be special quoted.
