Generally speaking, the proper use of plain bearings, the fatigue life can be achieved. But early damage if an accident occurs, it can no longer use. With different fatigue life, this early injury is called a fault or an accident. More due to the installation, use, consider the lubrication on the ill from outside intrusion of foreign matter or the shaft, bearing insufficient research.
State of the bearing damage such as roller bearing ring wall abrasions, which may be due to lack of lubricant, grade unsuitable for oil discharge structure defects, foreign invasion, bearing misalignment or shaft deflection is too large, there may also be caused by the reasons mentioned integrated.
Thus, the survey only bearing damage, it is difficult to know the real cause of injury. However, if you fully understand the use bearing machines, basic working conditions and its peripheral structure, clarify the situation before and after the failure, combined with the damage of bearings and a variety of reasons related to the analysis, it is possible to prevent similar failures again.
