These Pololu white plastic wheels have rubber tires measuring 42mm in diameter and press-fit onto the 3mm D output shafts on many of our motors, including our micro metal gearmotors and mini plastic gearmotors with 3mm D-shafts. Teeth on the hub optionally allow a reflectance sensor to be used for encoder feedback. These wheels are sold in pairs.
These rugged wheels are designed to press-fit securely onto the 3mm D output shafts of our micro metal gearmotors. They should be mounted onto the side of the hub with the protruding teeth, as shown in the images. 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.
The Pololu extended micro metal gearmotor bracket is specifically designed to work with this wheel. Please note that the non-extended version will not work well with this wheel.
