There are 2 main type slewing drives used for solar tracker: Enclosed Slewing Drive and Vertically-Mounted Slewing Drive. Slewing drive for solar tracking system application include Concentrator Solar Dish, CPV (Concentrated Photovoltaics), CSP (Concentrated solar power), solar parabolic heating collecting systems, single axis solar tracker and dual axis solar tracker.

Enclosed Slewing Drive Series

One worm shaft or two worm shaft option. Low speed and high torque performance. SE series size from 3” to 32” suited for different solar tracker size request. Can be connected with dc motor or planetary gear motor.
