A slewing drive is also called slewing gear drive or slewing reducer, etc. It is typically used in aerospace area, solar power systems, wind turbines, satellite broadcasting system, and engineering machinery like truck cranes, and man lifts, etc. Recently years, it has been prosperously used in photovoltaic power generation systems. 

When a slewing drive is used in solar energy industry, users have to choose an ideal one according to the actual area of solar panels. Broadly speaking, 3 inch slewing drive is suitable for solar power system coming with 3- 5 m2 solar panel, 7 inch for 10-17 m2 solar panel, 9 inch for 18-30 m2, 12 inch for 31-45 m2, and 14 inch for 46-60 m2. These are provided for your reference. For more specific and detailed information, please contact me directly.

A slewing drive is usually composed of a slewing ring, worm, casting housing, and standard components like bearing and bolts, etc. While used in photovoltaic power generation system, the slewing drive is usually used in combination with DC planetary speed reducer motor and AC speed reducer motor. While used in engineering equipment, it is regularly used in combination with hydraulic motor to function as power driving system.
