A turbomachine has a bearing in a bearing compartment (600). A first seal system (100) isolates the bearing compartment (600) and has: a first runner (112); a second runner (113); an inner seal (104) encircling the first runner (112); and an outer seal (105) encircling the second runner (113). The inner seal (105) has a static clearance (RCI) with the first runner (112). The outer seal (105) has a static clearance (Rco) with the second runner (113), greater than the inner seal static clearance (RCI). The first runner (112) has an inner portion (132) cantilevered inward. The second runner (113) has an outer portion (133) cantilevered outward.
