The Shark-2 Servo Gearbox (Continuous Mode) is powered by a Hitec HSR-M9382TH servo with a brushless motor and titanium gears. The gearbox is fully assembled and ready to install; the shaft rotates with increased precision and torque thanks to a 2:1 external gear ratio.

The housing with ball bearings isolates the load from the servo, protecting it from axial forces. The gearbox has M4 threaded holes on the housing and on the top hub for convenient mounting, compatible with the goBILDA® system. Ideal for speed and direction control in projects on Arduino, Raspberry Pi, R/C receivers or REV controllers.
