Bearing damage and countermeasures

Bearing damage
Generally, if the bearing is used correctly, it can be used until the fatigue life is reached. However, there may be accidental premature damage, and it may not be able to withstand use. This kind of early damage, as opposed to fatigue life, is the quality use limit called failure or accident. It is mostly caused by careless installation, use, and lubrication, foreign objects invaded from the outside, and insufficient research on the thermal effects of shafts and housings.
About the damage state of the bearing
The jamming of the ring and rib of the roller bearing can be considered as the cause. There may be insufficient lubricant, unsuitability, defects in the oil supply and drainage structure, foreign matter intrusion, bearing installation errors, and excessive shaft deflection. These reasons coincide. Therefore, it is difficult to know the real cause of the damage only by investigating the bearing damage. However, if you know the machinery used, the conditions of use, the structure around the bearing, and the situation before and after the accident, combined with the damage state of the bearing and several causes, you can prevent similar accidents from happening again.
