These white plastic wheels have silicone tires and measure 40 mm (1.57″) in diameter. They mount onto micro servo splines with 20 teeth and a 4.8 mm diameter, such as the splines on FEETECH’s FS90R micro continuous rotation servos and FT90R digital micro continuous rotation servos. This product is a pair of wheels.

These wheels are great for robotics, custom RC vehicles, or any other project you need to get rolling. They measure 40 mm (1.57″) in diameter and are designed for use with micro servos with 4.8 mm diameter splines with 20 teeth, such as FEETECH’s FS90R micro continuous rotation servos and FT90R digital micro continuous rotation servos. The combination can serve as a small, inexpensive, and easy-to-control drive system for a miniature robot. The wheel presses onto the servo spline just like a typical servo horn, and the small screw included with the servo accessory pack for mounting servo horns should be used to hold the wheel in place. The included silicone tires are also available separately.
Six mounting holes for #4 or M3 screws make it possible to use the wheel with our universal mounting hubs for 6mm, 8mm, and 1/4″ shafts, enabling these wheels to be used with our 37D Metal Gearmotors and stepper motors with compatible shafts. The slots in the six spokes fit #2 or M2 screws and allow additional accessories to be mounted to the wheel such as decorations or parts of an encoder system. The included silicone tires, which feature horizontal treads for improved traction, are also available separately.
We have similar wheels available in different sizes and colors and with different spline compatibilities:
We also carry an array of wheels compatible with 3mm D shafts:
