Patent ID: 7604239

Claim:
An assembly for sealing a bearing housing and a rotating shaft comprising an axis of rotation, the assembly comprising: a stator comprising: a first stator portion and a second stator portion aligned along a stator plane extending through a diameter of the stator and the axis of rotation; and a stator annular engagement flange extending in an axial direction comprising a stator groove on a radial side thereof; a rotor comprising: a first rotor portion and a second rotor portion aligned along a rotor plane extending through a diameter of the rotor and the axis of rotation; and a rotor annular engagement flange extending in an axial direction comprising a rotor groove on a radial side thereof; and an annular unitizing element comprising: a first unitizing element portion and a second unitizing element portion aligned along a unitizing element plane extending through a diameter of the annular unitizing element and the axis of rotation; a stator engaging member that engages the stator groove; a rotor engaging member that engages the rotor groove; and a rear member comprising a top edge, a bottom edge, and a side edge, wherein the side edge extends from the unitizing element to engage the stator; and two adjoining areas of differing diameter, one area corresponding to the rotor engagement member and the other corresponding to the rear member.
