Pololu Wheel Pair (Black 70×8mm)

These black plastic wheels press-fit onto the 3mm D shafts on many of our motors, including our micro metal gearmotors and our mini plastic gearmotors, to make a nice drive solution for small robots. The wheels have silicone tires and measure 70 mm (2.75″) in diameter. Two additional mounting holes for 4-40 screws make it possible to use the wheel with several of our universal mounting hubs. The wheels are sold in pairs.

These wheels are designed to press-fit securely onto the 3mm D output shafts on many of our gearmotors, including our micro metal gearmotors and our mini plastic gearmotors. The wheels have silicone tires and measure 70 mm (2.75″) in diameter. Two additional mounting holes for 4-40 screws make it possible to use the wheel with our universal mounting hubs for 3mm shafts, 4mm shafts, and 5mm shafts. The slots in the five spokes allow additional accessories to be mounted to the wheel (e.g. decorations or parts of an encoder system).
