Product Advantage

Slewing drives sit on the center axis rotation of the torque tube drive line, they can be set as close to the ground as the size of the solar panels will permit. This allows the shortest, strongest, and least expensive underlying structure to be built for supporting the solar trackers in the field, which is a considerable amount of the overall cost incurred.

Slewing drives rotate 360˚ continuously, so it's up to the solar tracking design engineer to limit their rotation at whichever angle is desired for the particular equipment. The selection is endless. For linear actuators though the size, cost, and approvals are unwieldy for anything more than +/-45˚.

Installation of a slewing drive is simply the fastening of the main structural bolts (normally four fasteners). There is no sub-assembly, post qualification, lubrication, inspection, or other work required. 

Slewing drives are shown to last 25-30 years in solar applications, with some models even available in a maintenance free version.
