Anti‐friction bearings (AFB) are found throughout all industrial facilities including mines andrncoal prep plants. In prep plants AFB are critical to the operation of all rotating equipmentrnincluding: electric motors, gear reducers, conveyors, fans and pumps. Mounted bearings describerna class of AFB that are contained in a self-supporting housing with a method of attaching thernbearing to a rotating shaft. This paper will discuss the different types of anti‐friction bearings and their application with specific emphasis on mounted bearings. Key topics of discussion includernbearing types and materials, bearing selection, bearing load and life calculations, and thernchallenges encountered when handling large bore bearings. Methods of attaching bearings tornshafts will be discussed as well as best maintenance practices for bearing storage, mounting andrnremoval. Lubrication and bearing sealing options and their impact on reliability will be reviewed.rnAn introduction to bearing failure analysis and how to use failure data to improve bearingrnreliability will also be presented. Examples of bearing failures will be reviewed to demonstraternthe processes and the solutions for each case will be presented.
