Built for rock-solid reliability and extended service life, every DUROCHAIN #208B roller chain is manufactured using premium carbon steel components, through-hardened pins, solid bushings, solid rollers, quad-staked rivets, precision-prepared plate holes, and factory-applied lubrication to help improve strength, wear resistance, shock-load capability, and overall operating performance.
DUROCHAIN Premium #208B Double-Pitch Metric 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.
Solid Bushings & Rollers
Precision solid bushings and solid rollers provide smooth cylindrical bearing surfaces that help reduce friction, resist deformation, and improve overall chain wear life.
Superior Plate Hole Preparation
Precision-pierced, shaved, and ball-drifted plate holes help promote accurate component fitment, improved pin-to-plate contact, and dependable holding strength.
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, side-load capability, shock-load resistance, and dependable performance in demanding industrial applications.
Factory Preload
Factory preloading helps properly seat and align chain components before installation, reducing initial elongation and promoting consistent operation once placed into service.
