The double-row ball slewing bearing can carry axial load, tilting moment and radial loads at the same time. The top ball mainly carries the axial load and positive tilting moment. Double row ball slew rings are ideal in applications where a high moment load is to be supported, a degree of rigidity is required in the bearing system, or there are high radial loads.
