These blue plastic wheels press-fit onto the 3mm D shafts on many of our motors, including our micro metal gearmotors and our plastic gearmotors with 3mm D-shafts, 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 for 4-40 screws make it possible to use the wheel with several of our universal mounting hubs. The wheels are sold in pairs.
