Angular contact ball bearings have inner and outer ring raceways that are displaced relative to each other in the direction of the bearing axis. This means that these bearings are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads. The axial load carrying capacity of angular contact ball bearings increases as the contact angle increases. The contact angle is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, along which the combined load is transmitted from one raceway to another, and a line perpendicular to the bearing axis. 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. Both inner ring halves of SKF Explorer four-point contact ball bearings have a recessed shoulder. This improves oil flow when the bearing is used in combination with an SKF cylindrical roller bearing. In addition, these recesses can be used to facilitate dismounting. Bearing Features: Accommodates axial loads in both directions. Less axial space - Can be used for applications where two single row angular contact ball bearings arranged back-to-back take up too much axial space. High load carrying capacity - A large number of balls are incorporated, giving the bearing its high load carrying capacity. Separable design - The split inner ring leads to easier mounting and dismounting of the bearing. Improved oil flow. Limited inner ring deformation when subjected to high clamping forces.
