Installation tips

High-speed precision angular contact ball bearings are mainly used for high-speed rotating occasions with light load, requiring high accuracy, high speed, low temperature rise and low vibration of the bearing and a certain service life. The supporting parts of high-speed motorized spindle are often installed in pairs and are the key accessories of high-speed motorized spindle of internal surface grinding machine.

Installation form

Angular contact ball bearings can provide selection, angular contact ball bearings installation form, back-to-back, face to face and series arrangement of three. When the two bearings are installed back-to-back (the wide end faces of the two bearings are opposite), the contact Angle line of the bearing spreads along the direction of the rotation axis, which can increase the radial and axial support Angle rigidity and maximize the deformation resistance. When installed face to face (the narrow ends of the two bearings are opposite), the contact Angle line of the bearing converges in the direction of the rotation axis, and the rigidity of the supporting Angle is small. Because the inner ring of the bearing extends out of the outer ring, when the outer rings of the two bearings are pressed together, the original clearance of the outer ring is eliminated, and the preload of the bearing can be increased. When the series arrangement (the wide end faces of the two bearings are in one direction) is installed, the contact Angle line 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, when using this installation form, in order to ensure the axial stability of the installation, the two pairs of bearings arranged in series must be installed at both ends of the shaft.
