The life of rolling bearings is defined by the number of revolutions (or the number of hours of work at a certain speed): bearings within this life should have initial fatigue damage (flaking or defect) on any of their bearing rings or rolling elements. However, no matter in the laboratory test or in actual use, it can be clearly seen that the actual life of bearings with the same appearance under the same working conditions is quite different. In addition, there are several different definitions of bearing "life", one of which is the so-called "operating life", which means that the actual life a bearing can achieve before failure is caused by wear, damage is usually not caused by fatigue, but Caused by wear, corrosion, seal damage, etc.
