Main Features:

1. High rigidity: Carburizing, carbon nitrogen co-carburizing, brilliant quenching heat treatment, the advantages of high productivity, good quenching.
2. High precision: Adopt advanced equipment,strictly controlled in quality and technology.
3. High torque:
(1) Front shell and tooth ring adopt integral design 
(2) Integrated design of planetary frame and output shaft 
(3) Bearing long span design, ensure the output load capacity 
(4) Full needle rolling, increase contact surface 
(5) Modular design of motor connection plate  
4. Low noise:
The helical tooth surface is modified for tooth shape and lead to reduce the impact and noise of gear on the input and output,
then increase gear service life greatly.
