Do you really know angular contact ball bearing arrangement

120 Published by Jul 03,2019

Angular contact ball bearings will exert an additional axial force when subjected to radial loads and can only limit axial displacement of the shaft or casing in one direction. Angular contact ball bearing arrangement: back-to-back configuration, face-to-face configuration, and series configuration.

Angular contact ball bearing arrangement--When back-to-back installation, the load it bears is separated from the bearing shaft, which is called to bear the axial load acting in two directions. This feature can better limit the axial displacement of the shaft. The load in one direction can only be withstood by one bearing. angular contact ball bearing arrangement:Back-to-back mounted bearings provide a relatively rigid bearing configuration with maximum resistance to deformation and different contact angles for the two sets of bearings--angular contact ball bearing arrangementangular contact ball bearing arrangement

Angular contact ball bearing arrangement--When face-to-face installation, the load it bears is converging to the bearing shaft, can withstand the axial load acting in both directions, and can also limit the axial displacement of the shaft. In each direction The load can only be withstood by one bearing. However, this configuration is not as rigid as the "back to back" configuration. In addition, the positioning of the parts on the "face-to-face" mounting shaft is not appropriate. When the shaft is heated and the bearing clearance becomes smaller, it may cause the top dead. For long stem shafts and large temperature rise during operation, "back-to-back" installation should be given priority--angular contact ball bearing arrangement

Angular contact ball bearing arrangement—The contact angles of the two sets of bearings should be exactly equal when installed in series. When using this type of mounting, the bearing set can only be used in one direction. angular contact ball bearing arrangement:axial load on the upper part. If the axial load acts in the opposite direction, it is necessary to add a third bearing that is opposite to the series-connected bearing. Usually, angular contact ball bearing arrangement:the axial displacement of the semi-balance and the limiting shaft ensures the stability of the installation. In addition, the bearing needs to be installed with bearings that can bear the axial load in the other direction, or two pairs of bearings arranged in series are mounted on opposite ends of the shaft.
