Description & Specifications
Nitro high-quality 120 roller chains are built for strength, durability and reliability. Our chains are manufactured from very specific carbon & alloy steel to achieve the highest level of wear & fatigue resistance through precise heat treatment & shot peening. Nitro #120 chain if fully compliant to the ANSI B29.1 standards, which outlines specific dimensional & strength requirements for Amercian roller chain sizes. ANSI compliance also ensures this chain is compatible with any ANSI #120 roller chain sprocket.
The 120-1R roller chain is commonly referred to as a 1-1/2" pitch chain, which is the pin to pin measurement.

Manufactured with solid cold-forged rollers for smoother contact with the sprocket teeth and to resist distorting under heavy loads.
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.
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.
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.
Advanced heat treatment is applied to achieve optimum hardness for strength and wear resistance.
To combat fatigue failure from repetitive loads & wear, a compressive stress layer is added through shot peening.
Product Care & Maintenance
Maintenance and lubrication is crucial in the overall performance and life span of roller chain. Proper lubrication will reduce abrasion, chain wear, friction, noise and keep chains running cooler at higher RPM's. You can download the Nitro Roller Chain Care below.
