Abstract
A seal plate for a gas turbine engine includes an annular wall provided about an axis and extending between first and second ends that are radially spaced from one another with respect to the axis. The first end includes an axially extending pilot. The second end includes an axially extending flange and an adjacent annular seal seat. The wall includes a portion between the first and second ends that extend substantially in the axial direction and is configured to permit the second end to move axially relative to the first end in response to thermal growth.
