Experience the DUROCHAIN Difference.
DUROCHAIN 120DC Double Capacity Roller Chain is designed for applications requiring increased load capacity while maintaining compatibility with standard #120 single-strand roller chain sprockets. With a 1.500" pitch and double capacity construction, 120DC provides a heavy-duty solution without requiring a wider multi-strand sprocket arrangement.
Built for rock-solid reliability and long-lasting performance, DUROCHAIN 120DC Double Capacity Roller Chain combines precision-manufactured components with additional side plates designed to increase overall chain capacity and working load. The result is a compact power transmission solution that delivers increased strength while maintaining the pitch and sprocket compatibility of standard #120 single-strand roller chain.
DUROCHAIN 120DC Double Capacity Roller Chain has a rated 75,265 LBS load capacity and is an excellent option when your application requires more capacity from a #120 pitch chain without changing to a multi-strand sprocket setup.
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.
