Four point contact ball bearings

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 four-point contact ball bearings have a recessed shoulder.

This improves oil flow when the bearing is used in combination with an cylindrical roller bearing.

In addition, these recesses can be used to facilitate dismounting.
