Swing Bearings

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.
Consequently the requirements for loading are stricter than ordinary bearings.
If the selection of the bearing has been wrong it will cause a great damage. Hence it is necessary to evaluate the exact forces acting on the slewing ring and to select the suitable slewing ring.
