Abstract
A radial shaft seal for a radial shaft is formed with a casing having an exterior-facing surface opposite from an interior-facing surface, and a sleeve positioned radially inwardly of the casing that rotates with respect to the casing. A sealing ring is connected to the casing, and has an extending portion that interacts with the sleeve to form a labyrinth seal barrier.
