ROLLING BEARING FAILURES - e Longo

2000-5-1  Seizing is one of the most common failure modes when bearings are first put into service. The lack of rolling element rotation results in a rapid and excessive rise in temperature. The surface hardness of the bearing races and rollers or balls is reduced, and the bearing is quickly rendered unsuitable for use. This is illustrated in Figure 11.
