The size of the slew drive is different, and its specification
model is divided based on the approximate raceway diameter of the
slew bearings: WD-080, WD-0130, WD-0170, WD-0223, WD-0343, WD-0419,
WD-0478, WD-0625 and other specifications. The naming standard of
the domestic model is according to the approximate raceway diameter
of the slew bearings, in inches (1 inch =25.4mm), is divided into:
SE3, SE5, SE7, SE9, SE12, SE14, SE17, SE21, SE25 and other
specifications. The "WD" representative in the foreign model
callout means: the abbreviation of Worm and drive, and the "SE" in
the domestic model callout: the abbreviation of Slewing and
Enclose. Regardless of the method of naming, the corresponding
mounting dimensions and performance parameters of each model are
the same.
Features & Applications
By adopting slewing bearing as its corecomponent,slewing drive can
bear axial force, radial force and tilting moment simultaneously.
Slewing drive is widely applied in modular trailers, all types of
cranes, aerial working platform,solar tracking systems and wind
power systems.
