Angular contact ball bearings can withstand both radial and axial loads simultaneously. Capable of operating at higher speeds. The larger the contact angle, the higher the axial bearing capacity. High precision and high-speed bearings typically have a contact angle of 15 degrees. Under the action of axial force, the contact angle will increase.

Single row angular contact ball bearings can only withstand axial loads in one direction, which will cause additional axial forces when subjected to radial loads. And can only limit the axial displacement of the shaft or shell in one direction. The contact angle of angular contact ball bearings is 40 degrees, so they can withstand significant axial loads.
