What is the difference between positive and negative installation of angular contact bearings?

What is the difference between forward and reverse installation of angular contact bearings? 

1. When two bearings are installed in pairs, the pressure center distance of reverse installation bearing is larger than that of forward installation. 

2. The front mounting structure is simple and convenient for disassembly and adjustment, while the reverse mounting structure is complex and inconvenient for disassembly and adjustment.

 3. When the transmission parts are cantilever mounted, the stiffness of the reverse mounted shafting is higher than that of the forward mounted shafting. 

4. The reaction force and deformation of the bearing installed in the front and the upper limit and deformation of the bending moment of the shaft are greater than those installed in the back. 

5. When the transmission parts are between the two bearings, the positive installation reduces the distance between the bearing pressure centers and helps to improve the shaft stiffness, while the reverse installation is the opposite. 6. Of course, the main difference is the different installation methods. Different installation methods also have a certain impact on all aspects of bearing performance. We should consider the appropriate installation methods when selecting.
