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

Swing bearings (slewing rings, slewing ring gears, swing ring, turn table bearings) for Komatsu, Hitachi, Kobelco, Caterpillar, Volvo/Samsung, Daewoo/Doosan & Hyundai Excavators.

Slewing rings are usually used for low revolution while shaking and strained with an enormous axial force, moment and in some parts with radial force simultaneously.
