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 The retaining ribs on the cones have beveled surfaces so that as the hub is withdrawn from the steering knuckle, in which case one of the cones will be carried along with the hub, the beveled surface on the cone that moves with the hub will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.

A roller bearing comprising an outer race having an inwardly presented tapered raceway, an inner race located within the outer race and having an outwardly presented tapered raceway located opposite the raceway for the outer race, the inner race further having a thrust rib at the large diameter end of its tapered raceway and a retaining rib at the small diameter end of its tapered raceway, the retaining rib having a beveled outwardly presented surface that leads away from the small end of the raceway for the inner race, increasing in diameter as it does; and rollers arranged in a row between the raceways of two races, with each roller having a large diameter end and a small diameter end, the large diameter ends of the rollers being adjacent to and normally abutting the thrust rib of the inner race and the small diameter ends being adjacent to the retaining rib of the inner race, the rollers and retaining rib being dimensioned and shaped such that as the inner race is withdrawn axially out of the outer race, the retaining rib will move the rollers axially a short distance until axial movement is blocked by means located adjacent to the large diameter end of the outer race, and whereupon the beveled surface on the retaining rib will deflect the small diameter ends of the rollers outwardly to an extent sufficient to free the inner race from the rollers and outer race.
