ONE of the objections attendant on the use of needle roller bearings, as illustrated in Fig. 1, has been overcome by the introduction of needle rollers having trunnion instead of spherical ends. In the type shown in Fig. 1, without adding considerably to the cost of the bearing, it is only with difficulty that the rollers can be kept in position during the process of fitting, whereas with the design illustrated in Fig. 2, by the employment of rollers having trunnion ends, they can be readily retained in the outer ring by means of pressings fitted into the bore of the shoulders, thus enabling the outer ring and rollers to be handled as a single unit during fitting.
