Three common installation methods for angular contact ball bearings

- May 15, 2020-

Angular contact ball bearings are one of the common types of bearings, so that everyone has a better and more comprehensive understanding of the installation of angular contact ball bearings, telling you that the three common installation methods of angular contact ball bearings are back-to-back, face-to-face and The installation method of series arrangement may choose different ways to install the bearing better and safer according to the use in different fields.


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

2. When face-to-face installation (the narrow ends of the two bearings face each other), the contact angle of the bearing converges toward the direction of the axis of rotation, and the rigidity of the support angle is small. 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 end faces 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 oppositely at both ends of the shaft.

Don't underestimate the installation of bearings. A good installation method can not only improve the efficiency of the bearings but also extend the service life of the bearings. Therefore, we must master the installation methods of angular contact ball bearings.
