Four-Point Contact Ball Bearings



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 These bearings take up considerably less axial space than double row bearings Both inner ring halves of SKF Explorer four-point contact ball bearings have a recessed shoulder This improves oil low when the bearing is used in combination with an SKF cylindrical roller bearing . In addition, these recesses can be used to facilitate dismounting. When four-point contact ball bearings are subjected to high clamping forces their inner ring deformation is limited.
