Slewing bearing is also called: Slewing ring bearing/ Turntable bearing/ Slewing ring etc. Slewing Ring Bearings can accommodate axial, radial and moment loads acting single or in combination and in any direction. They are not mounted in a housing or on a shaft, but directly to a seating surface. The inner and outer ring are supplied with mounting holes. Both rings may have integral gears. They are also referred to as slewing rings and tabletop bearings. Slewing ring bearing can perform oscillating (slewing) as well as rotating movements.  They may be used without gears or with internal or external gears.
