This custom-designed white plastic wheel from Pololu has a rubber tyre measuring 42 mm in diameter and is designed to fit the output shafts on our micro metal gearmotors. Teeth on the hub optionally allow a reflectance sensor to be used for encoder feedback. These wheels are sold in individually.

This rugged wheel is designed to fit securely on the output shafts of our micro metal gearmotors. These gearmotors should be mounted onto the side of the hub with the protruding teeth, as shown on the right. The output shaft will slide into the socket easily at first but will achieve a snug fit when pressed through to the other edge of the hub.

Our extended micro metal gearmotor bracket is specifically designed to work with this wheel.
