Extract from back cover of book:

Every working model includes bearings, often alarge number of them. This practical book describes the wide and diverse range of bearings found in the large variety of different types of models built in home workshops. It reviews the choice of bearings materials, the type of bearing to use for each particular application and highlights the differences between home-made and off-the-shelf bearings. It also considers the installation and care of bearings. Furthermore, it also covers several full-size applications undertaken by model engineers, such as clock making and machine tool maintenonce, which also call for some knowledge of bearings.
