Small Worm Gear Slewing Drives
Slewing ring drive for precision application: the success of our
slewing ring is the result of the precision of our finished slewing
drives by grinding and adjustable backlash design and technology.
Our zero backlash and small backlash series slewing drives'
production is perfectly under control and the matching of the rings
and the rolling elements. To ensure the clients can obtain the
right bearing for this very demanding application.

Applications
A solar tracker using a slewing drive is a mechanical device used
to align photovoltaic modules with the sun or direct sunlight to
photovoltaic cells. Photovoltaic trackers can be divided into two
types: non-concentrating photovoltaic (PV) trackers and
concentrating photovoltaic (CPV) trackers. Each of these two types
of trackers can be subdivided according to their number of tracked
axes, drive architecture and transmission, tracker application,
etc.
