Angular Contact Ball Bearing Installation Knowledge

The installation of angle contact ball bearings is more complex than that of deep trench ball bearings, and is mostly installed in pairs, and requires preloads. Well installed, can make the host's working accuracy, bearing life greatly improved;

The angle contact ball bearing is installed in three forms, back-to-back, face-to-face and series. When mounted with a back-to-back (the wide end face of the two bearings is relative), the contact angle of the bearing diffuses along the direction of the swing axis, which can increase its radial and axial support angle rigidity, and the resistance to deformation is greatest; Because the inner ring of the bearing extends out of the outer ring, when the outer ring of the two bearings is pressed together, the original gap of the outer ring is eliminated, which can increase the preload of the bearing, and when installed in series (the wide end of the two bearings in one direction), the contact angle of the bearing is the same and parallel, so that the two bearings share the working load in the same direction. However, in order to ensure the axial stability of the installation, two pairs of bearings arranged in series must be installed at both ends of the shaft.
