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](https://core-electronics.com.au/feetech-fs90r-micro-continuous-rotation-servo.html) and [FT90R digital micro continuous rotation servos](https://core-electronics.com.au/feetech-ft90r-digital-micro-continuous-rotation-servo.html). 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. | \| [ ![](https://core-electronics.com.au/attachments/localcontent/0J10773_26637421cf4.jpg) ](https://core-electronics.com.au/attachments/localcontent/0J10773_311667b8b17.jpg) \| \|---\| \| 60 mm and 40 mm Pololu Wheels for Micro Servo Splines on FEETECH’s [FT90R](https://core-electronics.com.au/feetech-ft90r-digital-micro-continuous-rotation-servo.html) and [FS90R](https://core-electronics.com.au/feetech-fs90r-micro-continuous-rotation-servo.html) micro continuous rotation servos. \| | \| [ ![](https://core-electronics.com.au/attachments/localcontent/0J10775_22790d9bbb7.jpg) ](https://core-electronics.com.au/attachments/localcontent/0J10775_2863576e962.jpg) \| \|---\|---\| \| 60 mm and 40 mm Pololu Wheels for Micro Servo Splines (21T, 4.8mm). \| | |---| Six mounting holes for #4 or M3 [screws](https://core-electronics.com.au/hardware/screws-nuts.html) make it possible to use the wheel with any of Pololu's [universal mounting hubs](https://core-electronics.com.au/hardware/mounts-hubs/hubs-clamps.html) for those screw sizes, enabling these wheels to be used with Pololu's [metal gearmotors](https://core-electronics.com.au/category/51/pololu-metal-gearmotors) and [stepper motors](https://core-electronics.com.au/components/motors/stepper-motors.html).
