A gas turbine engine (20) includes a rotor hub (60') which includes a substantially axially extending projection (82) and a substantially radially extending projection (84). A seal ring (72') includes a body portion (90) and at least one knife edge (76) that extends outward from the body portion (90). A recess (86) is in the body portion (90) for accepting the axially extending portion of the rotor hub (60'). The seal ring (72') includes at least one cooling passage that extends through the seal ring (72'). A lock ring (80) is in abutting contact with the seal ring (72') and the radially extending projection (84) on the rotor hub (60') for securing the seal ring (72') to the rotor hub (60').
