What is the installation process of annular ball bearings?

Angular contact ball bearings can withstand both radial and axial loads. Can work at higher speeds. The larger the contact angle, the higher the axial load carrying capacity.

annular ball bearings are available in back-to-back, face-to-face, and series arrangements. The outer ring of the angular contact ball bearing is thick on one side and thin on the other side. The thick side is called the "back" and the thin side is called the "face". It should be noted that the angular contact ball bearings are mostly installed in pairs and require preloading. The installation is good, the working accuracy and bearing life of the main machine can be greatly improved; otherwise, the accuracy will not meet the requirements and the service life will be affected.

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

2. When facing the surface (the narrow end faces of the two bearings are opposite each other), the contact angle of the annular ball bearings converges toward the direction of the rotation axis, and the ground bearing rigidity is small. Since the inner ring of the bearing protrudes from the outer ring, when the outer rings of the two bearings are pressed together, the original gap of the outer ring is eliminated, and the preload of the annular ball bearingscan be increased;

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