Single Axis Small Slew Drive Gearbox For 24VDC Drived PV Auto Tracking System
Small Slew Drive Description
The slewing drive is a slewing reduction mechanism with an integrated drive power source. The slewing bearing is used as the main transmission component. This product is also known as rotary reducer and rotary drive device. Compared with traditional rotary products, the rotary drive device is easy to install and maintain, and saves installation space to a greater extent. Mainly used in beam trucks, aerial work vehicles, industrial robots, photovoltaic power generation, wind power generation, engineering mechanical claws and other fields.

Selection of Slewing Drive
When selecting a suitable slewing drive, we need a brief information about the solar tracking system:
1. The scale of the projects. For utility-scale and large projects usually use horizontal single-axis solar trackers, while dual-axis trackers are mostly used in smaller residential applications.
2. The load on the slewing drives and its gravity distance
3. The output speed
