HG hollow shaft

The hollow output shaft of the HG planet gear speed reducer is designed with the installation of fewer teeth and is compatible with a smaller servo motor. Less torque is required to start operation and produce higher economic benefits. Ball screws can be directly installed with planetary gear reducers to reach higher accuracy.

Industry Applications

Smooth operation and low noise

Hardened and ground rack and pinion adopt helical and spur system.

High radial and axial load

Using high-quality taper roller bearing to strengthen the radial and axial load.

High dynamics

For an excellent design, high accuracy, and low moments of inertia.

Perfect for linear positioning

Adopting ground rack and pinion; cumulative pitch error 0.03/1000mm

Easy installation and weight saving

Pinion and output shaft of reducer are connected with high stiffness coupling。

Rack and pinion can be adjusted to the best precision

With eccentric plate and simplified structure could be adjusted the position of pinion easily.

High economical effect

Low moment characteristics could select the smaller kilowatt servo motor, further carry the cost-down out.

Long service life

Well design and structure
Using high-quality taper roller bearing
High-quality German seal
Harden and ground gear
Best-chosen synthetic oil
