 Angular Contact Ball Bearings bear both radial and axial loads.  Can work at high speed.  The larger the contact Angle, the higher the axial bearing capacity.  High precision and high speed bearings usually take 15 degrees of contact Angle.  Under axial force, the contact Angle will increase.  

 Folded into pairs of double ball bearings  

If it is installed in pairs, the outer ring of a pair of bearings is relative, that is, the wide end faces the wide end face, and the narrow end faces the narrow end face.  This avoids additional axial force and limits the shaft or housing to axial clearance in both directions.  

Because the raceway of its inner and outer ring can have relative displacement on the horizontal axis, so it can bear radial load and axial load at the same time - combined load (single row angular contact ball bearings can only bear single direction axial load, so they are usually installed in pairs).   

Cage materials are brass, synthetic resin, etc., according to bearing form, use conditions.   

The narrow side out, the wide side in, the other wide side in, the narrow side out, back to back.  
 

 Precision grade  

The accuracy grades of angular contact ball bearings include dimensional tolerance and rotation accuracy.  The accuracy from low to high is P0(ordinary), P6(P6X), P5, P4, and P2.  In addition, the European and American brands also use P3, P7, P9 precision level, P3 is equivalent to ISO and JIS standards of P6, P7 is equivalent to P4, P9 is equivalent to P2.
