These 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.
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 70 mm (2.36″) 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.
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 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 feature horizontal treads for improved traction
