Slewing Bearings
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 slowing bearing. It is mainly used in machines with low load and high use frequency, such as wharf tower crane.
