Angular contact ball bearings are able to support radial load and axial load. As single row angular contact ball bearings can only support axial load in single direction, matched bearing mounting is often adopted to them. As matched pairs of bearings, preload for them is more convenient. Retainers are made of brass, synthetic resins or others subject to individual bearing features and application conditions.
Double row angular contact ball bearings are a form of back -to-back pairs of single row angular contact ball bearings, which support axial load in both directions as well as support radial load.
With two piece inner ring, this type bearing can take axial load in both directions.
