摘要： An assembly (20) is provided for rotational equipment. This assembly (20) includes a seal device (38), a ring structure (48) and a fastener (122). The seal device (38) includes a plurality of seal shoes (61), a seal base (60) and a plurality of spring elements. The seal shoes (61) are arranged around a centerline (22) in an annular array. The seal shoes (61) include a first seal shoe (61). The seal base (60) circumscribes the annular array. The spring elements include a first spring element. The first spring element connects and extends between the first seal shoe (61) and the base (60). The ring structure (48) is axially adjacent the seal device (38). The ring structure (48) includes a fastener aperture (124) extending axially through the ring structure (48). The fastener (122) is mated with the fastener aperture (124) and abutted axially against the seal device (38).
