Double-Row Ball Type Slewing Ring

Slewdrive can also be called slew drive gearbox. Most of our slewing ring drive
is kind of worm gear reducer. And the slew ring bearing is a gear drive part.

The double row ball slewing bearing has three races. The steel ball and the
spacer block can be directly discharged into the upper and lower raceways.
According to the force condition, two rows of steel balls with different
diameters are arranged. This open assembly is very convenient, the upper and
lower circular races have a bearing angle of 90° and can withstand large axial
forces and tipping moments. When the radial force is greater than 0.1 times the
axial force, the raceway must be specially designed. The double-row and
different-diameter spherical slewing bearings have relatively large axial and
radial dimensions and are structurally fastened. It is especially suitable for
loading and unloading machines such as tower cranes and truck cranes that
require medium and large diameters.
