Description
The WEA series enclosed worm drive is an optimized and upgraded product on the basis of the WE series. With a fully sealed structure, this worm gear drive is able to meet the application requirements in the wild or in the indoor areas with high humidity.

Features
1. The housing of this series of worm drive has been optimized. It is thinner in thickness and higher in strength.
2. Owing to a fully sealed structure, our slewing drive can resist the corrosion of wind, sand, and water, thus being suitable for use in the wild where the working conditions are harsh.
3. The tooth contact area is large and the drive torque is high.
4. To better protect the worm gearing and prevent wrong selection of bolts, we change the screw hole from the original through hole into the current blind hole.

Supply Capacity
We can meet almost any worm drive customization requirements.

Application
The WEA series enclosed worm drive is widely used in the solar energy and machinery fields.
1. Photovoltaic and solar thermal power generation tracking systems
2. Rotation in the chassis of aerial vehicle
3. Drive the boom of truck crane to rotate
4. Drive the sand grasping machine to rotate
