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 a single direction, matched bearing mounting is often adopted to them as matched parts 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.
Angular contact ball bearing include:
1) Single row angular contact ball bearing
2) Matched angular contact ball bearing
3) Double row angular contact ball bearing
4) Four-point contact ball bearing
Angular contact ball bearings features :
1) Load capacities are higher than deep groove ball bearings of same dimensions;
2) Used for bearing radial-axial combined loads or pure thrust loads;
3) Low operating friction and high limiting speed.
