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

What is the difference between the normal and reverse installation of angular contact bearings?、
1. When two bearings are installed in pairs, the pressure center distance of the reverse installation bearing is larger than that of the normal installation.
2. The structure of the normal installation is simple and convenient for disassembly and adjustment, while the structure of the reverse installation is complex and inconvenient for disassembly and adjustment.
3. When the transmission parts are cantilevered, the stiffness of the reverse installation shaft system is higher than that of the normal installation shaft system.
4. The reaction force, deformation, upper limit of the bending moment and deformation of the normal installation bearing are greater than those of the reverse installation.
5. When the transmission parts are between the two bearings, the normal installation reduces the pressure center distance of the bearing and helps to improve the stiffness of the shaft, while the reverse installation is the opposite.
6. Of course, the main difference is the different installation methods of the two. Different installation methods also have a certain impact on the performance of various aspects of the bearing. We should consider the appropriate installation method when making specific selections.
