ABSTRACT:
A double row tapered roller bearing that is unitized for handling purposes is suited for installation over the drive flange of a front wheel drive automobile. The bearing includes a double cup, a pair of cones, tapered rollers arranged in two rows between the cup and cones, cages along each row of rollers, and seals at the ends of the cup. The seals have cases which are pressed into the ends of the cup and also have seal elements which contact the cones. Relatively little radial clearance exists between the press fitted portion of the seal case and the ring at the large end of the cage. Should a withdrawal force be applied to either one of the cones, such as when an attempt is made to strip a wheel flange from the bearing, the rollers of one row will drive the large end ring of the cage against the seal case so that the withdrawal force is transmitted through the cage to the case. Since the cage is closely confined by the press fitted portion of the seal case, the cage does not buckle significantly or fracture.
