Overview

These wheels are great for robotics, custom RC vehicles, or any other project you need to get rolling. They measure 60 mm (2.36″) 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.

Six mounting holes for #4 or M3 screws make it possible to use the wheel with any of our universal mounting hubs for those screw sizes, enabling these wheels to be used with our metal gearmotors and stepper motors. 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.
