Overview
The Renold 120-2RB duplex roller chain (model 120A2X10FT) is a high-performance transmission chain engineered for industrial machinery, conveyors, and power transmission systems. With a 1-1/2″ pitch and duplex (two-strand) construction, this chain delivers reliable torque transfer and longevity in demanding applications. The riveted pin design enables secure coupling while simplifying field installation and maintenance.
Key Features
- Duplex Configuration — Two parallel strands distribute load evenly, increasing load capacity and reducing strain on individual links.
- 1-1/2″ Pitch (120 ANSI) — Standard industrial spacing compatible with common sprockets and drive systems.
- Riveted Pin Construction — Eliminates need for cotters or clips; provides a secure, permanent joint with no disassembly risk.
- 10 ft Length — Ready-to-install length suitable for mid-range drive spans without additional assembly.
- Cold Forged Components — Solid bushings and wide waist link plates maximize wear resistance and tensile strength.
- ANSI B29.1 Compliant — Meets North American industrial chain standards for quality and interchangeability.
