Description & Specifications
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.

Features
Product Features Of Nitro™ 81X Chain
Premium quality chain with improved features that results in longer lasting chain over many competitors.
Solid Rollers
Smoother operation between the chain & sprocket as well as better lubricant retention between the roller & bushing.
Solid Bushings
Will not distort under heavier shock loads that results in less stretch.
Quad Staked Pins
Able to withstand more frequent and higher shock loads.
Solid Roller
Manufactured with solid cold-forged rollers for smoother contact with the sprocket teeth and to resist distorting under heavy loads.
Solid Bushing
Built with solid cold-forged bushings for superior wear resistance that results in service life 2x to 3x greater than split bushing chains. See the solid bushing advantage.
Quad Staked Pins
Pin ends are quad staked rather than the standard dual staked pins. Quad staking offers enhanced strength while enduring higher shock loads.
Pre-Loaded
After assembly, all Nitro chains are pre-loaded to a minimum load required by the industry standard. Pre-loading seats the chain joint that eliminates any initial elongation in a new chain.
Lubrication
Pre-lubricated in a special formulated lubricant through a hot-dipping process. This process is critical to ensure the lubricant penetrates and thoroughly coats the internals of the chain. The special lubricant offers better retention (less spin-out) and improved wear protection over chains that are cold-dipped.
Heat Treated
Advanced heat treatment is applied to achieve optimum hardness for strength and wear resistance.
Shot Peened
To combat fatigue failure from repetitive loads & wear, a compressive stress layer is added through shot peening.
Product Care & Maintenance
81X Roller Chain Lubrication & Maintenance
Roller chain lubrication is very critical to maximize the performance and life span of the chain. With proper lubrication and maintenance you'll reduce abrasion, chain wear, friction, noise and keep temperatures lower while running at higher RPM's.
