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.
