Double row angular contact ball Slewing Ring
Double row angular contact ball Slewing Ring have the features of two single row angular contact bearings back-to-back but with more compact design occupying less axial space. DRACBB accommodate high radial as well as axial loads, working in both directions. They enhance unit stiffness and accommodate tilting moments.
Double row angular contact ball Slewing Ring main structural characteristics: two rows of steel balls of different diameters are placed to bear the axial force and upsetting moment. The most prominent feature is flexible rotation, but its bearing capacity is lower than that of the triple-row cylindrical roller slewing bearing. It is mainly used in machines with low load and high use frequency, such as wharf tower crane.
