Light weight; compact structure; can accept axial force, radial force and tipping moment at the same time.

The size of the single-row ball slewing bearing is large, and its diameter is generally 0.4 to 10 meters, and some are as high as 40 meters. Slewing bearings generally have to accept loads from several aspects, not only axial force and radial force, but also a large overturning moment. Therefore, a set of single-row ball slewing bearings often plays the role of several sets of ordinary rolling bearings.
