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 will be accidents that are prematurely damaged and cannot be used. This early damage, as opposed to fatigue life, is a quality use limit called a fault or accident. Many of them are caused by inadvertent installation, use, and lubrication, and foreign objects intruding from the outside are insufficiently studied for the thermal effects of the shaft and the outer casing.

About the damage state of the bearing

Roller bearing ferrules, rib jams, as a cause can be considered, insufficient lubricant, unsuitable, defective oil supply structure, foreign matter intrusion, bearing installation error, shaft deflection too large, there will be These reasons overlap. Therefore, it is difficult to know the true cause of the damage by only investigating the bearing damage. However, if you know the mechanical use of the bearing, 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 reasons, it can prevent similar accidents from happening again.
