Model Number FE120-40N, Servobox Series Model FE120 2-Stage, 40 Ratio, and Solid Output Shaft Output Bearing Planetary Reducer Gearbox On Pelonis Technologies, Inc.

Integrated Planetary Arm Bracket
The planetary arm bracket and the output shaft are one-piece constructed to increase torsional rigidity and accuracy. The entire structure is machined for controlling accuracy in the specified tolerance.

Full Needle Roller Bearings Design
The planetary gear transmission employs full needle roller bearings without a retainer to increase the contact surface. This greatly improves structural rigidity and service life.
