These Pololu black plastic wheels have silicone tires and measure 70mm 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. Additionally, this wheel is compatible with several of our universal mounting hubs, which can serve as adapters for motors with different shafts. 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 70 mm in diameter and are designed to press-fit securely onto D output shafts with a diameter of 3 mm.

Two mounting holes for #4 or M3 screws make it possible to use the wheel with any of our universal mounting hubs for those screw sizes, enabling these wheels to be used with our larger metal gearmotors and stepper motors. The slots in the five spokes fit #2 or M2 screws and allow additional accessories to be mounted to the wheel such as decorations or parts of an encoder system.

This is the black version of our 70×8mm wheel pair. These same-sized wheels are also available in red, yellow, blue, or white. Motors and hubs not included.
