Zusammenfassung:	A seal assembly (60) includes a seal runner (74), at least one seal ring (84), and a seal housing (82). The runner (74) extends in an axial direction to a runner end face (76) that faces a bearing (62). The seal ring (84) is fixed to a static structure (70) and has an inner surface (86) engaging the seal runner (74) and a first face (90) that faces the bearing (62). The seal housing (82) is fixed to the static structure (70) and includes a first housing portion (98) extending in an axial direction from the first face (90) of the seal ring (84) to a housing end face (100) that faces the bearing (62). The first housing portion (98) has a first length (L1) extending from the first face (90) of the seal ring (84) to the housing face (100). The seal runner (74) has a first runner portion (108) with a second length (L2) that extends from the first face (90) of the seal ring (84) to the runner end face (76). The second length (L2) is at least 35% longer than the first length (L1).
