These white plastic wheels have silicone tires and measure 70 mm (2.75″) in diameter. They mount onto standard servo splines with 25 teeth and a 5.8 mm diameter, such as the splines on FEETECH’s FS5106R, Power HD’s AR-3606HB, and SpringRC’s SM-S4303R continuous rotation servos. This product is a pair of wheels.

We have similar wheels available in different sizes and colors and with different spline compatibilities:

Overview

These plastic wheels with silicone tires are 8 mm (0.3″) wide and 70 mm (2.75″) in diameter and are designed for use with standard servos with 5.8 mm diameter splines with 25 teeth, such as FEETECH’s FS5106R, Power HD’s AR-3606HB, and SpringRC’s SM-S4303R 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 wheels feature six mounting holes sized for #4 or M3 screws, one on each wheel spoke, with opposite pairs of holes spaced 19.1 mm (0.75″) apart. This spacing is compatible with our larger universal mounting hubs, which can serve as adapters between these wheels and the shafts on our larger metal gearmotors and stepper motors (see the table at the bottom of this page for information about which wheels are compatible with which universal mounting hubs). The pictures below shows these wheels with a universal mounting hub for 4mm shafts installed so it can work with our 20D or 25D metal gearmotors.

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.
