This 40 tooth servo gear is most commonly used to drive the 80 tooth hub gear, spaced 48mm away, in order to create a 2:1 ratio. This gear reduction will increase the torque at the hub gear to 2x what the servo produces. This gear may also be used to drive a 20 tooth pinion gear spaced 24mm away for a 2:1 overdrive if you’re set out to increase the rotation of the servo.
