Zusammenfassung:	A bearing housing for supporting a bearing within a gas turbine engine may generally include a mounting flange and a bearing support ring positioned radially inwardly from the mounting flange. The bearing support ring may be configured to at least partially surround an outer race of the bearing. The bearing housing may also include a support beam spaced axially apart from the mounting flange and the bearing ring, a plurality of inner spring fingers extending axially between the bearing support ring and the support beam and a plurality of outer spring fingers extending axially between the mounting flange and the support beam. At least a portion of each inner spring finger may be spaced apart radially from at least a portion of each outer spring finger. In addition, the inner spring fingers may be circumferentially offset from the outer spring fingers.
