2-5/8" Plastic Blue Wheel Futaba Servo Hub

New alternatives available! We have released our own servo wheels that we recommend over this product. In particular, our 70×8mm Wheel for Standard Servos has almost the same dimensions as this wheel (see the picture below for a side-by-side comparison).

2-5/8″ Futaba Servo Hub, Solarbotics 2-5/8″ SW-B Servo Wheel, and 70mm Pololu Wheel for Standard Servo Splines.

This plastic Futaba servo wheel is made to match standard Futaba servo splines (25T, 5.8 mm diameter), such as those on the SpringRC SM-S4303R and Power HD AR-3606HB continuous rotation servos. The wheel is molded from ABS and measures just under 2-5/8″ across by 0.3″ wide. With the included rubber band tire, the total wheel diameter is 2-5/8″. The wheel is available in blue, yellow, red, and black.

Our 60×8mm/70×8mm tires for Pololu wheels also fit this wheel, making them a suitable replacement for when the rubber band tires are worn from use. The Pololu tires also have grooves cut into them along the perimeter of the tire, which might help by providing a better grip in certain applications.

Included Parts

• Two rubber band tires (one is a spare)

Installation

To install the wheel, remove the screw on your servo’s output shaft, push the wheel onto the shaft, and reinstall the screw. For some servos, such as the SpringRC SM-S4303R, the wheel might be a tight fit and not push onto the servo output shaft. In such cases, please try the method shown in this video:
