Features N/A High Torque
Higher output torque is compared to spur gear planetary gear reducers.

High Stability
Employs high tensile strength alloy steel. Gear hardening is made for the entire gear which extends gear service life and maintains high accuracy after a long period of operation.

High Speed Reduction Ratio
The gear reducer is a modular design. The planetary gear box can be connected. The speed reduction ratio can reach over 1/10000.
