Features

Features

 N/A High Load-Bearing Capacity
High load-bearing capacity is achieved by a dual tapper bearing.

One-Piece Helical Gear Box
The gear box and internal ring gear are a one-piece construction design. The speed reduction mechanism employs helical gears that provide two times the meshing rate of teeth compared to regular spur gears. It operates very smoothly, has low noise, high output torque, and low backlash.

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.

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

Integrated Planetary Arm Bracket
The planetary arm bracket and the output shaft are a one-piece construction design that increases torsional rigidity and accuracy.
