The basic function of a bearing is to allow relative movement to occur between load-carrying surfaces, and there are various types available working on principles such as rubbing contact, rolling elements, fluid films, deflecting members and magnetic repulsion. The relationship between the allowable load and the speed for the various bearing types is compared with the way in which bearing loads change during the operation of variable speed machines. Various applications have also been studied to assess what bearing loads and rotational speeds would be expected in machines of different sizes. The information presented is intended to assist designers with bearing selection.
