 Angular contact ball  bearing's Installation techniques

High speed precision angular contact ball bearings are mainly used for high speed rotating occasions with light load. High precision, high speed, low vibration and certain service life of bearings are required. Usually used as the supporting parts of high speed electric spindle for installation in pairs, it is a key component of high speed electric spindle of inner surface grinding machine.
angular contact ball bearing 's installation

Type of installation

The quick and easy automatic selection of angular contact ball bearings is available. The installation of angular contact ball bearings consists of back to back, face to face and series arrangement. When the back to back (the wide end face of the two bearings is opposite) is installed, the contact angular line of the bearing diffuses along the direction of the rotating axis, which can increase the rigidity of the supporting Angle of the radial and axial direction, and the maximum deformation resistance. In face (the narrow end face of two bearings is opposite) installation, the contact Angle of the bearing converges towards the axis of rotation, and its supporting Angle is less rigid. Because the inner ring of the bearing extends out the outer ring, when the outer ring of the two bearings is pressed together, the original clearance of the outer ring is eliminated, which can increase the bearing's preloading load. When the two bearings are mounted in series (the wide end face of the two bearings is in one direction), the contact Angle of the bearing is 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, two pairs of bearings arranged in series must be mounted on opposite ends of the shaft.
