Customized Four-Point Contact

Four-point contact ball slewing ring bearings consist of an inner ring and an outer ring. The slewing ring is compact in design, light in weight, and adopts a four-point contact ball configuration, which has excellent dynamic load capacity and can bear axial, radial and tilting moment loads. Four-point contact ball slewing bearings are particularly versatile and are widely used in cranes, lifting equipment and other construction machinery.

  • Outer diameter: 602mm~4726mm
  • Ball diameter: 30mm~75mm
  • Rated load: 129kN~3410kN

Cages or spacers are usually found in four-point contact ball slewing ring bearings. In addition, the slewing ring bearing of the full complement ball structure is only used for large loads, so the full complement ball structure bearing has good load capacity and large friction force, which may cause scratches on the contact ball.
