These Pololu white plastic wheels have silicone tires and measure 40mm in diameter, and they press-fit onto the 3mm D shafts on many of our motors, including our micro metal gearmotors and our mini plastic gearmotors. This product is a pair of wheels.
These wheels are great for robotics, custom RC vehicles, or any other project you need to get rolling. They measure 40 mm in diameter and are designed to press-fit securely onto D output shafts with a diameter of 3 mm.
