Nitro #40 super premium 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 #40 SP 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.

Manufactured with one-piece solid cold forged rollers that offer smoother contact with sprocket teeth and will not distort under heavy loads.
Pre-lubricated in a special formulated lubricant through a hot-dipping process. This process ensures the lubricant penetrates and evenly coats the entire chain & chain joints. This results in better lubricant retention (less spin-out) that offers better wear resistance and improved service life over cold-dipped chains.
Advanced computer controlled heat treatment is applied to all critical parts to maximize the strength and wear resistance.
Parts are shot peened to add better fatigue resistance and helps prevents cracking from higher loads and wear from operation.
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.
