Characteristics and applications of angular contact ball bearings:
Angular contact ball bearings have a high speed limit and can withstand both radial and axial loads, as well as pure axial loads. Their axial load capacity is determined by the contact angle and increases with the increase of the contact angle.
Single row angular contact ball bearings can only withstand axial loads in one direction. When subjected to radial loads, additional axial forces are generated, and corresponding reverse loads must be applied. Therefore, this type of bearing is generally used in pairs.
Double row angular contact ball bearings can withstand large radial and axial combined loads and torque loads, mainly radial loads. They can limit the bi-directional axial displacement of the shaft or shell, with a contact angle of 30 degrees.
Paired installation of angular contact ball bearings can withstand radial and axial combined loads mainly based on radial loads, as well as pure radial loads. The series configuration can only withstand axial loads in a single direction, while the other two configurations can withstand axial loads in either direction. This type of bearing is usually selected by the manufacturer to be paired and submitted to the user. After installation, there is a pre press interference, and the ring and steel ball are in an axial pre load state, thereby improving the stiffness and rotational accuracy of the entire set of bearings as a single support.
