Abstract
An annular unitizing element has a rotor engaging member, a stator engaging member, and a rear member. The radially outer surface of the unitizing element has two areas of differing diameter, one corresponding to the rotor engaging member and the other corresponding to the rear member. The stator engaging member extends radially inward from the radially inner side of the annular unitizing element. A sealing assembly for sealing a rotating shaft and a bearing housing has a rotor having an annular engagement flange extending in an axial direction comprising a groove on a radial side thereof, a stator having an annular engagement flange extending in an axial direction comprising a groove on a radial side thereof, and an annular unitizing element having a stator engaging member, a rotor engaging member, and a rear member.
