Angular contact ball bearing can be submitted to both radial and axial loads.Limit speed id quite high,contact angle can be 15°,25° and 40°,more contact area caused more axial load.

Double-row angular contact ball bearing can be submitted to bigger radial load and can limit the double direction axial displacement,four-point contact ball bearing have QJ and QJF designs,it has high rated load and speed and can be submitted to both radial and axial loads.

This kind of bearing is apply for milling and machine shafts.
