AmpFlow Wheel/Gearmotor Combinations
The AmpFlow Wheel/Gearmotor combination can be configured with your choice of five different wheel sizes and five different motors.

The custom hub is keyed to the wheel and also to the 3/4-inch shaft of the speed reducer. The wheel is assembled with 1/4-inch keys and held in place by two aluminum discs and a spacer. The whole assembly is held together by a 5/16-18 screw that threads directly into the shaft.

The 12.5-inch wheel has a 3/4-inch hub that slips onto the shaft of the speed reducer.

This combination of high power, high traction, and light weight make these wheels ideal for robots and other mobile applications.
