Angular contact ball bearings are one of the common types of bearings. In order to give you a better and more comprehensive understanding of the installation of angular contact ball bearings, I will tell you that the three common installation methods of angular contact ball bearings are back-to-back, face-to-face and The installation method of the series arrangement, according to the use in different fields, may choose different methods for better and safer bearing installation.

1. When installed back-to-back (the wide end faces of the two bearings are opposite), the contact angle of the bearings spreads along the axis of rotation, which can increase the rigidity of the radial and axial support angles and have the largest resistance to deformation;

2. When installed face to face (the narrow end faces of the two bearings are opposite), the contact angle of the bearings converges toward the axis of rotation, and the ground bearing angle is less rigid. Because the inner ring of the bearing protrudes from the outer ring, when the outer rings of the two bearings are pressed together, the original clearance of the outer ring is eliminated, which can increase the preload of the bearing;

3. When installed in series (the wide ends of the two bearings are in one direction), the contact angles of the bearings are in the same direction and parallel, so that the two bearings can share the working load in the same direction. However, when using this type of installation, in order to ensure the axial stability of the installation, two pairs of bearings arranged in series must be installed opposite each other at both ends of the shaft.

Do not underestimate the installation of bearings. Good installation methods can not only improve the use efficiency of bearings, but also extend the service life of bearings. Therefore, we must master the installation methods of angular contact ball bearings.
