The Stingray-9 Servo Gearbox (Continuous Mode) is driven by a goBILDA® 5-Turn Torque servo with a 9:1 external gearbox, which reduces the rotational range and increases torque and precision. The gearbox is fully assembled and ready for installation; the PWM signal controls the speed and direction of the output shaft.

The ball bearing shaft design isolates the load from the servo, protecting it from axial forces, and the housing with M4 threaded holes is compatible with the goBILDA® system. This gearbox is ideal for projects that require a powerful drive with speed and direction control.
