ABSTRACT:
A seal assembly having first and second annular seal elements each having a generally axially extending base and an annular radial lip. Each of the bases includes a wear surface portion, a central portion and an end portion. Each of the annular radial lips extend from a respective end portion. Each of the central portions include at least one bore therethrough. The first and second seal elements are mounted on respective members and are arranged such that the wear surface portion of each seal element provides a wearing surface for the radial lip portion of the other seal element. Furthermore, when assembled, the seal assembly forms a fluid tight annular cavity between this first and second annular seal elements and the bores permit the passage of a fluid medium into and out of the annular cavity.
