About the life of motor bearings

Bearings are an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy.

In actual use, the bearing life is related to the working environment, temperature and so on. Bearings are accompanied by the operation of the motor, and when the life of the bearings ends, serious quality failures will occur in the motor.

Usually, the metal fatigue of the rolling contact surface is the main cause of rolling bearing damage. More importantly, the bearing should be systematically managed and analyzed, such as the influence of bearing cage, raceway and lubrication and other related factors. These factors It plays a vital role in the life of the bearing.

Any kind of product has its service life, because it is difficult to avoid the influence of external factors during its operation. Moreover, for two sets of bearings with the same specifications and models, it is almost impossible to have complete consistency in their operating environments, so it is difficult to determine whether the two can have the same service life.

It can only be determined that "if the application conditions are harsh or used improperly, the life of the motor bearings will be greatly shortened."
