lifetime of bearings

For a single bearing, the number of revolutions of one ring relative to another or the number of working hours at a certain speed before the first sign of fatigue propagation occurs in the material of one ring or rolling element is called the bearing life. A large number of experiments have shown that even under the same working conditions, the lifespan of a batch of bearings with the same model is quite discrete, with some differences reaching several tens of times. Therefore, the lifespan of a certain bearing cannot represent the lifespan of a batch of bearings of the same model. When calculating the lifespan of bearings, it is necessary to be related to a certain degree of reliability (or failure rate), that is, when discussing the lifespan of bearings, it must be clear that it is the lifespan relative to a certain degree of reliability.
