Everyone has 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 experience in angular contact ball bearing manufacturers Taking contact bearings as an example, we sort out the installation misunderstandings that you will encounter in practical application when installing bearings: 1. Mistakes in bearing capacity Double row angular contact ball bearings can bear both axial and radial loads, and the bearing capacity of radial loads lies in the size of the contact angle. However, single row angular contact ball bearings can only bear axial load on one side. If the force is applied in the opposite direction, the bearing may be scattered. Therefore, in the actual bearing selection and bearing installation process, if the two-way conformity For 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 they have been dealing with light loads, they can still have a relatively good service life. However, if the preload is too large, the bearing load will be too large, the friction will increase, and the bearing may be locked, which will shorten the service life of the angular contact ball bearing. If the backlash is too large, it will cause noise and vibration. At this time, the precision of the equipment is difficult to guarantee. At the same time, the number of roller bearings bearing the force inside the bearing will be reduced, so that the bearing has the risk of premature failure. , so in actual application scenarios, if the bearing is installed in a single row, it must be ensured that it cannot handle high loads all the time. 3. Pairing application of angular contact ball bearings When the axial load is too large, we often use two angular contact ball bearings connected in series to increase the load. In specific applications, because angular contact ball bearings have large tolerances in aspect ratio and azimuth dimensions, when two bearings must be used together, paired bearings should be used.
