  • Patent number: 4466623
    Abstract: A steering ball seal includes a rigid annular outer case having a radially extending elastomeric sealing member bonded thereto. The sealing member includes a pair of sealing lips which extend radially inwardly of the case. The sealing member further includes an integral annular protective assembly tab which extends axially thereof and which contains a radially protruding retention ridge. The sealing member also includes an integral retention bead radially outwardly of the ridge. The lip and bead cooperate to provide for resilient insertion and removal of an inner case which is retained against the radial body of the sealing member to provide rigidity of the member during operation of the seal. In a preferred form, the inner case is of resilient polyethelene material, and includes a split body construction to facilitate its installation over the steering ball.
