Bearing failure modes: causes, and prevention methods

In general, if rolling bearings are used correctly, they will survive to their predicted fatigue life. Bearings, however, often fail prematurely due to avoidable mistakes. The causes of this premature failure include improper mounting, mishandling, poor lubrication, entry of foreign particles, and abnormal heat generation.
