Double row angular contact ball bearing: 

Double row angular contact ball bearing is a non-separable bearing, which can bear large radial and axial bidirectional combined loads and moment loads mainly based on radial loads, 

and can limit the bidirectional load of the shaft or housing Axial displacement, the contact angle is usually 30°, and it has better rigidity compared with single row bearings. 

Double row angular contact ball bearings

The structure is equivalent to a pair of back-to-back single-row angular contact ball bearings, but with a narrow width, it is especially suitable for applications with high rigidity requirements. Double row angular contact ball bearings generally use nylon cages or brass solid cages.
