3 inch slewing drive is our smallest model product and it is a very popular product which is used for small 3-8㎡solar tracking application and small solar dish.
Coresun Drive are using deep groove ball bearing instead of needle bearing on both side of slewing gear ,which can improve mechanical efficiency,precision and rotate more smoothly for slewing drive.
Coresun Drive has improved the performance of 3 inch slewing drive, so the total output torque tilting moment torque and holding torque is much stronger than original one.The key point of solar tracker system is tilting moment and holding torque.
