How to avoid failure of SKF roller bearing when used

The SKF aligning roller bearing has two rows of rollers, a common raceway with spherical outer ring and inner race raceway at an angle at the bearing axis. The center point of the sphere in the raceway of the outer ring is on the bearing axis. Therefore, bearings, self aligning and insensitive shaft relative to the shell, it can, for example, cause the shaft to be misaligned. This will cause the bearing to fail in the process of use. We should avoid such a thing and how to avoid it. Let me tell you all about it.
1. Selection and control of shaft and bearing tolerances: bearing should be flexible and no blockage after pressing. If the rotation is not obvious, it indicates that the shaft size is too large and the tolerance should be reduced. If the shaft is loaded into the shaft, it has a significant sense of “rustle” when rotating with the hand. It may be that the tolerance of the shaft is too large or the roundness of the shaft is not good. So when controlling the tolerance of shaft and bearing, the roundness must also be controlled.
2, the prevention of the assembly of foreign objects: when the bearing is loaded on the rotor, it is very easy to enter the inside of the roller bearing with the iron chips which are produced by the dynamic balance, so it is better to balance the bearings before loading the bearings. The metallurgical quality of the roller bearing material was the main factor affecting the early failure of the rolling bearing. With the progress of Metallurgical Technology (such as vacuum degassing of bearing steel), the quality of raw materials has been improved. The proportion of raw material quality in bearing failure analysis has obviously decreased, but it is still one of the main factors affecting bearing failure. Proper selection is still a factor to be considered in bearing failure analysis.
3, paint rust prevention: the characteristics of lacquer rust is multiple in the sealing type of motor, the motor in the assembly sound is very good, but after some time in the warehouse, the electric motor varies greatly, the dismantled bearing has serious rust phenomenon. Bearing life and manufacturing, assembly, use are closely related, must be done in every link, only in the use of adjustable roller bearings to pay attention to these points of attention, in order to make the bearings in the best running state, thus prolonging the life of the bearing. In order to ensure that the bearing has been running in good condition, regular maintenance and maintenance is necessary, so as to prevent accidents and unexpected, improve production efficiency and save cost. To be engaged in the professional maintenance of bearing, it is necessary to have a standard system operating process, including running state, lubricants, periodic disassembly, noise, temperature, and so on.
Above is the way I tell you to prevent SKF roller bearing from being used, and I hope you can remember it well and prevent it in time.
