ANGULAR CONTACT BALL BEARING
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.
Single-Row Angular Contact Ball Bearings
The structure of angular contact ball bearings produces an axial component when a radial or combined load is applied; therefore, two opposed bearings or a multi-bearing arrangement are used. A preload is often used to increase the rigidity of single-row angular contact ball bearings, particularly in the main spindles of machine tools where high running accuracy is crucial.
Double-Row Angular Contact Ball Bearings
A back-to-back paired mounting of single-row angular contact ball bearings is turned into a bearing with a single inner ring and outer ring. Double-row angular contact ball bearings are often used as fixed-end bearings as they can sustain axial loads in both directions and have the capacity to take moment loads.
Four-Point-Contact Ball Bearings
Four-point-contact ball bearings feature an inner ring split into two pieces. Just one of these bearings can sustain significant axial loads in both directions.
SINGLE ROW ANGULAR CONTACT BALL BEARINGS
Incorporating a large number of balls to give it a relatively high load carrying capacity, these bearings can accommodate axial loads in one direction only, are typically adjusted against a second bearing and have non-separable rings.

DOUBLE ROW ANGULAR CONTACT BALL BEARINGS
With a design corresponding to two single row bearings arranged back-to-back, but where two single bearings take up too much axial space, they can accommodate radial and axial loads in either direction and tilting moments.

FOUR-POINT CONTACT BALL BEARINGS
Designed to support axial loads in both directions and have a high load carrying capacity, these bearings can support a limited radial load for a given axial load, use less axial space than double row bearings and are separable.
