Features
Solid Bushing & Roller
Manufactured with both solid rollers and solid bushings, which offers better wear resistance and longer service life. See the advantages of using chains with solid bushing over split bushings
Solid Roller
Manufactured with one-piece solid cold forged rollers that offer smoother contact with sprocket teeth and will not distort under heavy loads.
Pre-Loaded
After assembly, all chains are pre-loaded to seat the chain components and eliminates any initial elongation on a new chain.
Thicker Link Plates
Heavy series chains are built with thicker link plates over the line of standard roller chain. This helps increase fatigue resistance, allowing the chain withstand higher and repetitive shock loads.
Lubrication
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.
Heat Treated
Advanced computer controlled heat treatment is applied to all critical parts to maximize the strength and wear resistance.
Shot Peened
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.
