These black plastic wheels press-fit onto the 3mm D shafts of our various gearmotor to make a nice drive solution for small robots. The wheels have silicone tires and measure 60 mm (2.36″) in diameter. Two additional mounting holes make it possible to use the wheel with our universal mounting hub 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).
The wheels are sold in pairs.
