Four-Point Contact Ball Slewing Ring Bearing

Contact Now

Four-point contact ball bearings are radial single row angular contact ball bearings with raceways that are designed to support axial loads in both directions. For a given axial load, a limited radial load can also be supported . The bearings are separable, i.e. the outer ring with ball and cage assembly can be mounted separately from the two inner ring halves. Both inner ring halves of the  Explorer four-point contact ball bearings have a recessed shoulder. This improves oil flow when the bearing is used in combination with a cylindrical roller bearing. In addition, these recesses can be used to facilitate dismounting.

The four-point-contact ball bearing is a single row angular contact bearings designed to handle two-directional axial loading. These bearings require a minimum amount of space and can be custom designed to meet our customer's unique loading parameters. And the four-point-contact ball bearings can carry either pure axial loading or combined loading provided the axial component is more significant.

For heavy industrial requirements, this style of bearing can be designed as a large slewing ring bearing with bolted down races and internal or external integral gearing.
