Usually; if the bearing is used correctly; can be used until the end of the fatigue life is stopped. But there will be accidental premature injury; the condition that is not used. This early damage; relative to the fatigue life; is called fault or incident The quality of the application of the limit. Due to the inconvenience of the device, the application, the lubrication; the foreign matter invading from the outside; the research on the thermal influence of the shaft and the outer casing is not sufficient.
The damage condition of the bearing is as follows: the ferrule of the roller bearing and the shank of the rib; the reason can be considered; the lack of lubricant, the unsuitability, the disadvantage of the oil supply structure, the intrusion of foreign matter, the bearing device error, the shaft deflection The song is too big; there will be coincidences.
Therefore; only the bearing damage is inquired; it is difficult to know the true cause of the damage. However, if the bearing is used, the operating conditions, the structure around the bearing, and the condition before and after the attack are known; the damage condition of the bearing and several causes are investigated.
