Description
For slewing drive, there are 10 different sizes available from 3" to 25" with more than 60 models to meet both regular and precise tracking requirements in PV system like oblique tracking system, flat single tracking system, CPV and solar thermal power tracking fields. Our slewing drives have higher output torque and holding moment torque, have excellent tracking precision, anti corrosion coating and anti UV sealing, IP66 protection class, and widely used in PV, CPV, CSP systems.
We has strict quality control system in our own factory, we have passed ISO9001-2008 quality system certification and meet with our country’s engineering & machinery standards.
Application
Solar dual-axis tracking system，the sun can be tracked in both the sun's altitude and azimuth, the most solar energy can be obtained, and full tracking, that is, dual-axis tracking, is designed according to such criteria. Compared with the optimal inclination angle power generation system, the dual-shaft power generation can increase by 25% to 40%.
Dual axis tracker is suitable to use in the middle-high latitude areas for residential, commercial, industrial or utility scale solar power generation sectors. Its high precision let the system fully automatic tracking in a higher precision manner to achieve approx 45% more power output than fixed mounting system. And easy installation, handling and maintenance.

Q&A
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 maximum 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 information such as backlash, IP grade demand etc
Should there be any area which you feel should be brought to our attention you can mail me info@helin-bearing.com
