These black plastic wheels press fit onto the 3mm D shafts of our mini and micro metal gearmotors to make a nice drive solution for small robots. The wheels have silicone tires and measure 90 mm (3.54") in diameter. Six additional mounting holes make it possible to use the wheel with several of our universal mounting hubs. The wheels are sold in pairs.
