GearMe gear motors including fan drives

Available in many sizes

Our GearMe gear motors are the ideal choice for a wide range of applications - from small to medium and large off-highway vehicles.

Available in three different frame sizes our aluminum gear motors feature high strength extruded aluminum housings, an aluminum rear cover and a front flange for a maximum strength and a low weight.

A broad variety of configurations are available with European or SAE flange options to meet widely varying machine requirements.

Our GearMe gear motors are designed to achieve significant improvement in overall efficiency. Use them to power your work functions and see your energy consumption reach a new low.

Our fixed displacement GearMe AL gear motors put your machine to work – providing maximum strength at minimum weight in the right frame size for your requirements.
