Double row angular contact ball bearings

The design of double row angular contact ball bearing is almost totally same as that of the single row angular contact ball bearing. However, its axial dimension is relatively small.So,the double row angular contact ball bearings can be considered to a pair of back-to-back single row bearings. It can bear axial loads in two directions as well as torques.

Double row angular contact ball bearings usually have fitting solt, the side of the raceway without fitting solt must carry main loads when bearings are in use.

Please kindly post your comments,we will attach great importance to it,and give our reply quickly.Thank you.
