ABSTRACT:
A fluid seal for use between a stationary member and a rotating member. A rigid member mounted on the stationary member has a peripheral cylindrical portion joined to a peripheral frustoconical portion. A sealing assembly mounted on the rotating member has a supporting case and a radial flange. An elastomeric body is bonded to the flange and has, to one side of the flange, a radially outwardly projecting frustoconical auxiliary lip engaging the peripheral cylindrical portion. A main sealing lip, comprising an annular, flexible, polytetrafluoroethylene planar wafer, is bonded to the body on the other side of the flange from the auxiliary lip. This main lip extends radially outwardly, the wafer normally tending to assume a substantially radial position. One face of the wafer engages and is flexed by the frustoconical portion. The centrifugal force of the rotating member in either direction tends to urge the lips more snugly against the rigid member.
