There are many misunderstandings about bearing installation in actual use. It is very important to install and select suitable bearings in different application scenarios. Installation errors will affect the efficiency of bearing use and the life of bearings. 37 years of angular contact ball bearing manufacturer experience Taking contact bearings as an example, we have sorted out the installation misunderstandings that the bearing will encounter in practical applications: 1. Bearing capacity misunderstandings Double row angular contact ball bearings can withstand both axial and radial loads, and the bearing capacity of radial loads lies in the size of the contact angle of view. However, single row angular contact ball bearings can only bear the axial load on one side. If the force is supported in the opposite direction, the bearing may disperse. Therefore, in the actual bearing selection and bearing installation process, if the two-way conformity is satisfied, choose Single row angular contact ball bearings, in practical applications, the bearing life may be greatly reduced. 2. Misunderstanding of the actual relationship between preload and service life of single-row angular contact ball bearings For single-row angular contact ball bearings, assuming that it has been dealing with light loads, it can still have a better service life. However, if the preload is too large, the bearing load will be too large, the sliding friction will increase, and the wheel may lock up in the bearing, thereby reducing the service life of the angular contact ball bearing. If the backlash is too large, it will cause noise and vibration. At this time, it is difficult to ensure the precision of the machine and equipment. At the same time, the number of roller bearings that bear the force inside the bearing will be reduced, so that the bearing has the risk of premature failure. , so in the actual application scenario, if the bearing is installed with a single row, it must be ensured that it cannot handle a high load all the time. 3. Pairing application of angular contact ball bearings When the axial load is too large, we often use the method of connecting two angular contact ball bearings in series to increase the load. In specific applications, because the angular contact ball bearing has a large aspect ratio and azimuth dimension tolerance, when two bearings must be applied together, a paired bearing should be selected.
