Model Number SDD64-70-P2, Servobox Series Model SDD64 2-Stage, 70 Ratio, Standard Output Bearing, and P2 Backlash Class Planetary Reducer Gearbox


Quiet Operation
Helical gears reduce vibration and noise.

High Precision
Backlash ≤ 3 arc·min reaches precision alignment.

High Rigidity and Torque
High rigidity and high torque are achieved by integrant needle roller bearings and a one-piece construction.

Features
One-Piece Gearbox Housing
The gearbox and internal ring gear are a one-piece construction. High gear accuracy meets DIN6 class.

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

Collet Locking Mechanism
The input-end and the motor are coupled through a collet locking mechanism that ensures concentricity and balance on the connection and no backlash for power transmission while running at high speed.

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.
