1.The definition of single row angular contact ball bearing
Single row angular contact ball bearings can accommodate axial loads acting in one direction only . Under radial loads a force acting in the axial direction is produced in the bearing, and this force must be counteracted. Consequently the bearing is normally adjusted against a second bearing.
2. Features of angular contact ball bearings
Angle contact ball bearings can be subject to both radial and axial load: it also can be subject to pure axial load, its axial load capacity is depend on the contact angle and increased accordingly .It can be used for high speed and high precision application due to high limit speed and pre-adjustable rigidity.
Single row angular contact ball bearings are self-retaining units with solid inner and outer rings and ball and cage assemblies with polyamide, sheet steel or brass cages. The raceways of the inner and outer rings are offset in relation to each other in the direction of the bearing axis. The bearings are available in open and sealed versions. Their self-alignment capacity is very small.
Double row angular contact ball bearings are units with solid inner and outer rings and ball and cage assemblies with polyamide, sheet steel or brass cages. They correspond in design to single row angular contact ball bearings in pairs in an O arrangement but give a narrower design than these. They differ in the size of their contact angle and the design of the bearing rings.
The bearings are available in open and sealed versions. Due to the production technology used, open bearings can still have turned recesses on the outer ring for seals or shields. Sealed bearings are maintenance-free and, as a result, allow particularly economical bearing arrangements. The self-alignment capacity of angular contact ball bearings is very small.
Spindle bearings are single row angular contact ball bearings comprising solid inner and outer rings and ball and cage assemblies with solid window cages. They cannot be dismantled. The bearings are available in open and sealed versions.
Spindle bearings have restricted tolerances. They are particularly suitable for bearing arrangements with very high requirements for guidance accuracy and speed capacity. They have proved highly suitable for the bearing arrangements of spindles in machine tools.
Four point contact ball bearings are single row angular contact ball bearings and therefore require significantly less space in an axial direction than double row designs.
3.The application of angular contact ball bearing
These bearings are mainly applied in the machine tool spindles, high-frequency motors, gas turbines, oil pumps, air compressors, printing machines and other installations.
