Turntable bearings (sometimes referred to as slewing ring bearings) are 4 point contact thin section type ball bearings that have holes in both the inner and outer rings for easy mounting.   These products were designed from standard thin section bearing geometry.  We just reduced the ID and increase the OD to accommodate bolt holes.   Our intention was to make the bearing easy to mount in an industrial application.  One that would require no additional machining (i.e., turning or grinding) of mating components for proper installation.
