Industrial 141K485G01 Double Idler Synchronous Timing Belt Pulley With Shaft

The 141K485G01 Double Idler Synchronous Timing Belt Pulley with Shaft is a shaft-mounted, double-pulley assembly designed to guide and tension timing belts in synchronous belt drive and motion-control systems. Constructed from steel or aluminum alloy with a steel shaft, it accepts timing belts (toothed/synchronous belts) and features a free-spinning idler to maintain belt alignment and slip-free power transmission in continuous-duty industrial environments. This pulley's double-idler configuration reduces belt wear and helps preserve accurate positioning in conveyors, packaging machinery, robotics, factory automation, and OEM equipment where precise timing is essential. It serves as a reliable replacement or retrofit part for worn idlers and timing-belt drive upgrades, and is listed under brand Generic/Industrial with the part number 141K485G01. Common replacements include Gates Timing Belt Idler Pulley Assembly, Martin Synchronous Timing Idler Pulley, and SDP/SI Double Timing Belt Idler Pulley with Shaft. The assembly is designed for shaft mounting, timing belt compatibility, and continuous-duty operation in industrial environments and is available as New Old Stock (NOS) or New Open Box.
