Model Number FB220-4, Servobox Series Model FB220 1-Stage, 4 Ratio, and Standard Output Bearing Planetary Reducer Gearbox


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.

Features
High Precision Gear Machining
The planetary gear and sun gear are manufactured from high quality Ni-Cr-Mo alloy steel (SNCM220), precision machined and carburizing heat treatment to hardness 57-60 HRC. Precision teeth grinding or skiving ensures gear accuracy reaches DIN6 class.

One-piece Gear Box Housing
The gear box and internal ring gear are one-piece constructed. High gear accuracy meets DIN6 class.
