These 80×10mm black plastic wheels press-fit onto the 3mm D shafts on many motors, including the micro metal gearmotors and mini plastic gearmotors, 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.
Note: The 80×10mm wheels are a perfect addition to the Balboa 32u4 balancing robot. They provide enough clearance for the balancing robot chasis to perform operations and work well with the 50:1 micro metal gearmotors. The wheels are made from ABS (also known as Polylac) PA-747.
