Rolling bearings are used billions of times around the world and have become an indispensable part of mechanical engineering. The expectation of the service life of such bearings is correspondingly high. The service life depends on various factors. Of course, the selection of the correct bearing type and the required dimensions play a central role here. However, the correct installation method and maintenance (lubrication) are often underestimated, forgotten or even ignored. In practice, many rolling bearings fail at an early stage of their service life and do not achieve the originally calculated or estimated service life by far. More than 60% of all premature bearing failures could be avoided. Looking at different investigations regarding the cause and frequency of bearing failures, they can be divided into the following groups:
