Open housing slewing drive (S type)


The Open housing slewing drive is composed of the open type base, slewing bearing, enveloping worm and the completed spare parts. The Electronic motor and hydraulic motor can be all used as the power input source for slewing drives, which can make CCW and CW rotation.


Open housing slew drive mainly apply to the lower working condition, such as no high requirement for the dust-proof, rain-proof and anti-corrosion. It was widely used on aerial platform vehicle and truck crane. The open housing slewing drive can reduce the cost compared with the enclosed housing slewing drive.

DRE can provide the open housing slewing drive from 3inch to 25inch. Please click the model number to check the drawing.
