A gas turbine engine includes a shaft and a heatshield that circumscribes the shaft. The heatshield defines a cylindrical body that has radially inner and outer sides and extends between first and second axial ends. The heatshield is exclusively supported on the shaft at the first and second axial ends. The heatshield includes at least one seal member on the radially outer side. A damper member is disposed at the radially inner side of the heatshield for attenuating vibration of the heatshield.

A seal assembly for a gas turbine engine includes a seal carrier and a seal press fit within an inner diameter of the seal carrier. The seal includes an outer ring supporting a radially moveable shoe supported by at least one beam. The outer ring includes an inner radial surface having at least one tab extending radially inward toward the shoe for aiding removal of the seal from the carrier.
