R32HT (Ball Bearing)

R32 32mm Planetary Gearbox with Ball Bearings

R32HT Ball Bearing Mini Motor Gearhead

R32HT (Ball Bearing)

The R32HT gearbox is a full metallic high torque gearhead designed with a planetary arrangement for applications requiring very high torque in a relatively small package. The R32HT can deliver max continuous torque up to 9Nm. Due to its lower backlash feature, it is ideally suited for precision motion requirements in various applications. Along with the planetary geartrain benefits, its unique bearing system provides good strength for applications that have higher radial loads.
