Pololu Wheel Pair (Black 80×10mm)

These black plastic wheels press-fit onto the 3mm D shafts on many of our motors, to make a nice drive solution for small robots. The wheels have silicone tires and measure 80 mm (3.15″) in diameter. Six 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.

The left picture below shows a slightly larger version of this wheel mounted to a 37D mm metal gearmotor with a universal mounting hub for 6mm shafts, and the right picture below shows a slightly larger version of this wheel mounted to a micro metal gearmotor.

We also have wheels this same size that use interchangeable collets to work with four different shaft types (3mm D, 3mm round, 4mm D, and 4 mm round), and the collets also grip the shafts more tightly than similar press-fit wheels.
