What is the installation feature of angular contact bearings back to back?

The difference in the way the angular contact bearings back to back is the difference in the point of force. The force point is as shown in the figure, which is the intersection of two lines.

1. When the angular contact bearings back to back DB is installed, the load acting center is outside the bearing center line; when the face-to-face DF is installed, the load acting center is within the bearing center line;

2. When the angular contact bearings back to back DB is installed, the force action point span is larger, so the cantilever end is more rigid. When the shaft is heated and extended, the bearing clearance is increased, the bearing will not be stuck and destroyed; when the face-to-face DF is installed, the structure is simple. It is convenient to disassemble and disassemble. When the shaft is heated and extended, the bearing clearance is reduced, which is easy to cause the bearing to be stuck. Therefore, special attention should be paid to the adjustment of the bearing clearance;

 

3. The load lines of the angular contact bearings back to back are separated from the bearing shaft. It can withstand axial loads acting in both directions, but the load in each direction can only be absorbed by one bearing. Back-to-back mounted bearings provide a relatively rigid bearing configuration and can withstand overturning moments.

 

Usually, in order to balance and limit the axial displacement of the shaft, the other angular contact bearings back to back needs to be fitted with a bearing that can bear the axial load in the other direction.
