Industrial LHYJS-4B125Y-Y1-60 Shaft Mount Speed Reducer

Sumito LHYJS-4B125Y-Y1-60 is a hollow-shaft, taper-grip shaft-mount speed reducer with a 60:1 reduction ratio that delivers a 29 RPM output. Built on the 4B125 frame size, this Sumito reducer is designed for compact industrial power transmission tasks where motor speed must be reduced to provide slower, torque-focused output in a small footprint. The Y prefix denotes a shaft-mount, hollow-shaft configuration, and the taper-grip interface provides a secure connection to the driven shaft. With a 60:1 gear ratio, the unit enables precise low-speed operation for applications requiring controlled indexing or material handling in automated systems. This LHYJS-series component aligns with Sumito’s line of gear reducers for compatibility with matching accessories and configurations in industrial automation.
