Abstract
An interlocking labyrinth sealing assembly for sealing about a rotary shaft. The assembly includes a stator element having a forward extending lip which forms a radially inward extending groove and a rotor element which has a flange which extends outwardly about the lip and includes a downwardly depending rim which extends into the groove to place and maintain the rotor in a desired position relative to the stator so that a labyrinth seal is established between the rotor and stator. The lip of the stator also includes a sloped guiding surface to outwardly deflect the flange of the rotor so that the rim may be positioned within the groove.
