The outer cylindrical portion is metal and includes a radially inwardly extending locking member at the distal end thereof and the inner cylindrical portion has a radially outwardly extending O.D. sealing lip. The locking member and sealing lip provide an interference fit therebetween and must snap past one another to lock the seal elements together and unitize the thrust bearing.
