Double row angular contact ball bearings
The design of double row angular contact ball bearings is basically the same as that of single row angular contact ball bearings. However, the axial size is relatively small. Double row angular contact ball bearings have good rigidity, can bear bidirectional axial load, and can also bear a certain overturning moment. Its practical effect is similar to the two single row angular contact ball bearings arranged back to back. similar.
Double row angular contact ball bearings consist of an outer ring and an inner ring (or two inner rings).
