The RPP synchronous belt, with its reinforced parabolic tooth profile, is recognized as the quietest in the industry and is ideal for a wide range of applications. Fiberglass tensile member reinforcement ensures high torque power transmission, minimal elongation, and high flexibility while the high-quality chloroprene rubber compound provides excellent wear resistance and increased service life. A self-lubricating nylon fabric gives exceptional wear protection to the belt teeth.

Features & Benefits
