This custom-designed black plastic wheel has a silicone tire measuring 2.75" (70 mm) in diameter and is designed to fit the output shafts on Pololu micro and mini metal gearmotors.
These wheels are sold in pairs.
These black plastic wheels press-fit onto the 3mm D shafts of our Pololu mini metal gearmotors, micro metal gearmotors, and 120:1 mini plastic gearmotor 90-degree 3mm D-shaft output to make a nice drive solution for small robots. The wheels have silicone tires and measure 70 mm (2.75") 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).
