Three common installation methods for angular contact ball bearings

Angular contact ball bearings are one of the most common types of bearings. In order to let everyone have a better and more comprehensive understanding of the installation of angular contact ball bearings, I will tell you three common installation methods for angular contact ball bearings. The installation methods are back-to-back, face-to-face and tandem arrangement respectively. According to the use in different fields, different methods may be selected for better and safer installation of bearings.

1. When installed back-to-back (the wide ends of the two bearings face each other), the contact angle of the bearings spreads along the direction of the axis of rotation, which can increase the rigidity of the radial and axial support angles and maximize the resistance to deformation;

2. When installed face-to-face (the narrow end faces of the two bearings face each other), the contact angle of the bearings converges toward the direction of the rotation axis, and the rigidity of the ground bearing angle is small. Since the inner ring of the bearing extends out of 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 tandem arrangement (the wide ends of the two bearings are in one direction), the contact angle lines 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 to each other at both ends of the shaft.

The installation of bearings should not be underestimated. A good installation method can not only improve the efficiency of the bearing, but also prolong the service life of the bearing. Therefore, we must master the installation method of angular contact ball bearings.
