Abstract

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 (R<CI>) with the first runner (112). The outer seal (105) has a static clearance (R<CO>) with the second runner (113), greater than the inner seal static clearance (R<CI>). The first runner (112) has an inner portion (132) cantilevered inward. The second runner (113) has an outer portion (133) cantilevered outward.
