Abstract: A seal assembly is disclosed that can be used to seal a bearing case in a turbine. The seal assembly has an annular seal plate seated within a groove defined in the bearing case and radially-offset from the turbine shaft. A seal retainer is mounted on the shaft axially-offset from the annular seal plate and defines a channel therein for receiving and seating a seal therein. The seal has a flexible lip that extends from the body of the seal and engages either the inside surface of the bearing case or a counterface of the annular seal plate, thereby preventing or substantially restricting the influx of contaminants into the bearing case.
