Abstract

A seal assembly (60) for a gas turbine engine (20) includes, a seal arc segment (66), a sealing portion (72), a first rail (74R-1) and a second rail (74R-2) opposed to the first rail. The sealing portion extends in a circumferential direction between opposed mate faces in an axial direction between a leading edge (72LE) and a trailing edge (72TE). Each of the first and second rails extend outwardly in a radial direction from the sealing portion (72) to respective first and second edge faces (74RF-1, 74RF-2), and the sealing portion (72) has a sealing face (72A) dimensioned to bound a gas path (GP) and includes a backside face (72C) opposed to the sealing face. Each of the first and second rails includes at least one interface bore (74B) dimensioned to receive a retention pin (84).
