Installation Skills Of Angular Contact Ball Bearings

High-speed precision angular contact ball bearings are mainly used in high-speed rotating occasions with light loads, requiring bearings with high precision, high speed, low temperature rise and low vibration, and a certain service life. It is often used as the supporting part of the high-speed electric spindle and installed in pairs. It is a key accessory for the high-speed electric spindle of the inner surface grinder.
Angular contact ball bearings can be selected quickly and easily, and there are three installation forms of angular contact ball bearings: back-to-back, face-to-face and tandem arrangement. 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 has the largest resistance to deformation; face-to-face (the narrow ends of the two bearings face each other) During installation, the contact angle of the bearing converges toward the axis of rotation, and its support angle 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 clearance of the outer ring can be eliminated, which can increase the preload of the bearing; , 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 to each other at both ends of the shaft.
