Nitro #120-2 SP (Super Premium) double roller chain has increased strength & fatigue resistance over standard ANSI roller chains. On average our super premium roller chains are 28% stronger than standard chains. The improved strength is achieved by material, dimensional changes, manufacturing process and heat treatment. Our #120SP-2 roller chain is best for applications that encounter heavy & repeated shock loads. Connecting links for all super premium roller chains have pressed fit side plates, so the integrity of chain is not compromised.

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.
