R13 Sleeve Bearing Mini Motor Gearhead
R13 (Sleeve Bearing)
Our R13 is a full metallic 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 having higher radial loads.
