R22 Mini Motor Gearhead

R22 - R22 Mini Motor Gearhead

R22

Our R22 is a full plastic gearhead designed with a planetary arrangement for applications requiring high torque in a relatively smaller package. 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.
