BRIEF DESCRIPTION
Slew drives are used for concurrent transmission of axial
and radial forces, as well as transmission of tilting
moments. Slew drives consist of a ball or roller slewing
ring, hydraulic or electric drives, and a completely enclos-
ing housing. Force is transmitted to the mounting struc-
ture through bolts. For this purpose through holes or
threads are provided in the inner and outer ring.
OVERVIEW

Series SP slew drives are designed with spur gear and
straight toothing.
WD-L SERIES (LIGHT SERIES)
The lighter series is designated as the WD-L series. The
drive motor (hydraulic/electric) is optional. Additional
optional components are potentiometers, permanent
