DUROCHAIN Premium Roller Chain Features
Through-Hardened Pins
DUROCHAIN pins are through-hardened for increased strength, improved wear resistance, and dependable performance throughout the service life of the chain.
Precision Solid Round Parts
Solid bushings and rollers provide consistent bearing surfaces to help reduce internal wear, improve energy transfer, and support longer-lasting chain performance.
Superior Plate Hole Preparation
Precision-prepared plate holes help promote accurate component fitment, reduce stress points, and improve overall fatigue resistance in demanding applications.
Max Contour Side Plates
Max contour side plates are designed to add strength where it matters while maintaining ANSI dimensional requirements for proper interchangeability.
Quad-Staked Rivets
High-hold quad-staked rivets help improve chain integrity under shock loads, side thrust, and demanding operating conditions.
Factory Preload
Factory preloading helps seat chain components before installation, reducing initial elongation and helping the chain settle in faster once installed.
