These plastic wheels have silicone tires, measure 90 mm (3.54″) in diameter, and they press-fit onto the 3mm D shafts on our micro metal 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 90 mm (3.54″) in diameter and are designed to press-fit securely onto D output shafts with a diameter of 3 mm.

Six 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 six 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. The included silicone tires feature horizontal treads for improved traction.
