The products are widely applied in the producing equipments of all kinds of industries inside and outside China. They are the best choices for nowadays modern facilities of mechanical reducing drive control to realize large twisting distance, large gear ratio, little noise, high efficiency and stability.


-High quality die casting aluminum alloy housing, suitable for universal mounting.
- Heat sink design for cooling provides great surface area and higher thermal capacity than the casting iron housings.
- 8 sizes from 030 to 130, with power scope rom 7.5w to 60kw.
- Larger speed ratio range. each single frame size has 12 ratios from 5:1 to 100:1.
- Hardened worm with fine grinding has the features of higher efficiency and big output torque.
- Low noise and stably running, can adapt long term work condition in terrible environments.
- Light weight, high mechanical strength.
