R16 (Ball Bearing)

R16 16mm Plantary Gearbox with Ball Bearings

R16 Ball Bearing Mini Motor Gearhead

R16 (Ball Bearing)

Our R16 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 that have higher radial loads. Customized shaft lengths, special lubricants, and mounting flanges are all available for the R16 mini motor gearhead.
