Features
Engineered to Outlast.
Built to Perform.
Every component is precision-manufactured and rigorously tested — delivering maximum strength, wear life, and reliability under the toughest conditions.
Hardened Link Plates
Hardened link plates deliver superior fatigue strength, engineered to absorb repeated shock loads and high-impact forces.
Solid Rollers
Cold-forged solid rollers ensure smooth, uniform sprocket engagement and resist deformation — even under extreme loads.
Solid Bushings
Cold-forged solid bushings provide 2–3× the service life of split-bushing chains through vastly superior wear resistance. See the advantage →
Factory Pre-Loaded
Every chain is loaded to industry-standard minimums after assembly — seating all joints to eliminate initial stretch right out of the box.
Heat Treated
Advanced thermal processing achieves optimum hardness across all components for peak strength and wear resistance.
Shot Peened
A compressive stress layer is applied to critical surfaces, dramatically increasing fatigue resistance against cracking from repetitive loads.
Hot-Dip Lubrication
A proprietary hot-dip process drives lubricant deep into every pin and bushing interface — delivering better retention and wear protection than lightweight oil alternatives.
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.
