Gear Ratio 78 / 1 SDE 12 Dual Axis Slew Drive Biaxial For Dual Axis Sun Solar System


Dual axis slew drive (SDE type) - Solar tracker slew drive

The SDE series designing is absorbs the advantages of VE and SE. The Azimuth and Elevation 3D direction rotating at the same time.
The most common slewing drive application for the dual-axis slewing drives are dual-axis solar trackers, such as heliostats and concentrated photovoltaics (CPV), and satellite or radar dishes. Other applications include automotive lifts, robotic arm positioners, and stage equipment.



Our base model sizes deliver performance ranges from 1,500 Nm to 11,200 Nm of holding torque, 100Nm to 20,000 Nm of output torque, 5000 Nm to 89,000 Nm of tilting torque, and gearbox reduction ratios of 30:1 up to 150:1. By attaching a planetary gearbox, the gear ratio could be even higher. The drives can be mounted horizontally, vertically, or on a combination of multiple axes.




Our SDE dual-axis slewing drives are assured for a 30-year field life time of precise 3D positioning. SDE drives create an efficient and reliable solution in a single drive. We qualify all of our components and raw materials using standards set by ISO 9001, CE certifications to maximize field life.




Our slew drives use patented hourglass worm technology to give maximum control and movement support. Our worm gears engage 5 to 11 teeth on the pitch line of the ring gear from the hourglass screw, which is higher tooth engagement than standard worms, giving the gearbox greater stability and strength. Learn more about hourglass technology.


By adoping hourglass worm, the drives have the following features: 


1) Higher output torque and holding load


2) Top tracking precision


3) Strong corrosion resistance and sealing effective

How to choose the proper size of slewing drives?


Choosing a proper size of the slewing drives in order to avoid from not only performance lack or performance surplus is play an important role in achieving cost effective solutions.


Please give us the following information in order to select a suitable slewing drive:


1. the application

2. the output toque required. If you do not have a clear idea of that data, just tell us the load, for example, the weight of panels and the mounting brackets on our slewing drive.

3. the load dimensions and the biggest wind in your area in the past 10 years which are used to calculate if the drive we recommended could bear the maxium load when there comes the big wind. 

4. the output speed you required which will help us to recommend the suitable motors for you.

5. other informations such as backlash, IP grade demand etc
