These white plastic wheels have rubber tires measuring 42 mm (1.65?) in diameter and press-fit onto the 3mm D output shafts on many of our motors, including our micro metal gearmotors and our 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 gearmotors should be mounted onto the side of the hub with the protruding teeth, as shown in Photos. 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.
These wheels will also work with our mini plastic gearmotors with 3mm D-shaft outputs if the gearmotor is mounted to the other side of the wheel.
Our extended micro metal gearmotor bracket PO1089 is specifically designed to work with this wheel. Please note that the non-extended version of our mounting bracket PO989 will not work well with this wheel.
