Angular contact ball bearing types:

 single row angular contact ball bearing:only bear a direction of the axial load. In bear radial load, can cause additional axial force must be applied to the corresponding reverse load, therefore, the bearings are generally used in pairs

double row angular contact ball bearing: Can bear larger in radial direction load primarily radial, axial two-way joint load and torque load, it can restrict shaft or shell two-way axial displacement, the contact Angle is 30 degrees.

 four point angular contact ball bearing: also withstand torque load, with the single row angular contact ball bearing and double row angular contact ball bearing function

Paired configuration of angular contact ball bearing have three kinds of different configuration pattern:

(1) Back-to-back configuration,rear code is DB, The configuration of the rigid good, bear overturning moment performance good, bearing can be subject to bi-directional load

(2) Face to face configuration,rear code is DF, This configuration rigidity and the ability to withstand overturning moment as DB configuration form, the bearing can be subject to bi-directional load

(3) Series configuration,rear code is DT, This configuration also available in the same bearing place series three or more bearing, but only under single direction of the axial load
