Pololu Wheel 42x19mm Pair

by Pololu

This custom-designed white plastic wheel is designed to fit the output shafts on our micro metal gearmotors.

  • Rubber tire measuring 1.65" (42 mm) in diameter
  • Teeth on the hub optionally allow a reflectance sensor to be used for encoder feedback.
  • These wheels are sold in pairs.
Gearmotors 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
