A single row tapered roller bearing capable of taking radial loading as well as thrust loading in both axial directions has a cone provided with an integral thrust rib at the small diameter end of its raceway, a cup surrounding the cone, tapered rollers between the raceways of the cup and cone, a separate rib ring at the large diameter end of the cup raceway, and a cage for maintaining correct spacing between the rollers in the circumferential direction. The cage at one end has an outwardly directed lip which is too large to fit through the rib ring and at its other end has outwardly directed tabs which are too large to fit through the cup without deflecting. In effect, the cup and rib ring are captured between the lip and tabs on the cage, and since the rib ring and cup cannot separate, the rollers and cone remain in place, providing a bearing which is unitized sufficiently for normal handling. |
