In a wheel mounting a hub rotates within a steering knuckle or other carrier on a double row tapered roller bearing of the indirect configuration. This bearing includes a double cup that is fitted into the carrier, a pair of cones that are pressed over the hub, tapered rollers arranged in two rows between the opposed raceways of the cup and cones, and a cage for each row of rollers. The retaining ribs on the cones have beveled surfaces so that as the hub is withdrawn from the steering knuckle, in which case one of the cones will be carried along with the hub, the beveled surface on the cone that moves with the hub will deflect the small ends of its rollers outwardly to enable the cone to pass through the rollers and free itself from the cup without shearing off snap rings or similar devices that secure the cup in place.
