The elastomeric body has an inner flexible, annular seal lip which engages an inside cylindrical surface of the bearing cup and an outer seal bead and an outer flexible, annular seal lip which engage outside surfaces of the bearing cup. The sealed bearing arrangement includes a hardened steel washer inside the bearing cup which is engaged by an end of the metal washer of the seal assembly to protect the inner flexible, annular seal lip against damage or interference by needle bearing rollers inside the bearing cup.
