ABSTRACT:
A universal joint has a primary seal and a secondary seal. The universal joint includes a cross and a bearing cup with the cross having a body and a trunnion and an annular shoulder with an adjacent surface of circular cross section at the juncture of the body and the trunnion. The open end of the cup has at least one leg extending outwardly therefrom. The primary seal comprises a resilient sealing member having spaced lips engaging the cup and the cross. The secondary seal is spaced outwardly from the primary seal and has a ring with a leg extending outwardly therefrom. The leg of the secondary seal is in overlapping relationship with the leg of the cup. The ring has a tight fit with the adjacent surface of the cross body, with a top of the ring engaging the shoulder of the cross. The secondary seal is spaced slightly from the cup to enable lubricant flushed past the primary seal to escape.
