Single—row angular contact ball bearing will have axial component force when bearing radial load.For this reason,two bearings should be used back to back or face to face.
A contact angle exists between rings and balls,The standard contact angles are 15° ,25° and 40° .The bigger the standard angle is ,the higher the capability to bear axial load will be.The bigger the contact angle is,the more advantageous to rotate it will be.
Single—row bearing can bear axial load and unidirectional axial load.
Double—row angular contact ball bearing has such two types of structure as one outer ring with two inner rings and one outer ring with one inner ring.
DB combination.DF combination and double—row bearing can bear radial load and bi—directional axial load.DT combination is applicable to occasions where unidirectional axial load is high and the rated load of a single bearing is not sufficient.
Two single—row angular contact bearings combined back to back in structure have common inner and outer rings,capable of bearing axial load and bi-directional axial load.
Angular contact bearing is suitable for rotation at a high speed and accuracy.
Such bearings are mainly applied to main shafts, high frequency motor,internal combustion turbine,oi| pump,air compressor,printing machinery,etc.
