A seal assembly for a rotary machine which includes a rotor assembly having a rotatable rotor shaft is disclosed. The seal assembly may comprise a spacer, a seal plate, a ring seal, and a ring seal midplate. The spacer, the seal plate, and the ring seal midplate may be rotatable with the shaft and extend outwardly from the shaft. The ring seal is free and provides a seal for a bearing compartment of the rotary machine. The ring seal midplate is not attached to the spacer or the seal plate during a hardface process which is applied to any component of the seal assembly. The ring seal midplate may be longitudinally located between the spacer and the seal plate and be radially spaced between the ring seal and the shaft. |
