WEA Series Slew Drive
WEA series slewing drive is a new series of slewing product, also named as slewing reducer. It is commonly composed of worm, slewing bearing, housing, motor adapter, end cap and other components. By adopting slewing bearing as its core component, slewing drive can bear axial force, radial force and tilting moment simultaneously. Comparing with SE series slewing drive, WEA series have the advantages of better protective performance, great transmission torque, better impact resistance and long service life.
WEA series slewing drive is widely applied in the relatively rotary parts of machinery and solar energy field, including solar tracking system, rotary chassis of aerial working machinery, truck crane, rock drill, drilling machine, grasping wood machine.

-
Horizontal Installation
In solar applications, it is recommended to mount the slewing drives upside down on the azimuth axis for better protection and to add protection for the elevation axis.
-
Vertical Installation
In solar applications, it is recommended to install the slewing drives referring to the attached drawing for better protection.
