    The single row four point contact ball slewing rings is composed of two seat rings, which design in compact structure and light weight, steel ball contact with the circular raceway at four points; it can bear the axial force, radial force and the tilting moment at the same time.

    It can be used for slewing conveyor, welding manipulator, light & medium duty crane, excavator, and other construction machinery.

    Four-point contact ball bearings are single row angular contact bearings designed to handle two-way axial loads. These bearings require minimal space and can be custom designed to meet customers' unique load parameters. And the four-point contact ball bearing can carry a pure axial load or a combined load as long as the axial component is more important.

    For heavy industry requirements, this type of bearing can be designed as a large slewing bearing with a bolted seat and an internal or external integral drive.

    Bearing function:

    Adapt to axial loads in both directions

    Smaller axial space

    These bearings are subjected to less axial space than double row bearings.

    High load carrying capacity

    A large number of balls make the bearings have high load carrying capacity.

    Separable design

    The split inner ring makes it easier to install and remove bearings.

    Improve oil flow

    Limited inner ring deformation when subjected to high clamping force.


    Three types of this kind of slewing bearing:

    A. Without gear bearing

    B. External gear bearing

    C. Internal gear bearing
