Abstract

A bearing support cage includes: an annular forward ring (234); an annular aft ring (238); an annular mounting flange (236) disposed between the forward and aft rings; an annular array of axially extending first spring fingers (240) interconnecting the forward ring and the aft ring; and an annular array of axially extending second spring fingers (242) interconnecting the mounting flange and the aft ring wherein the first spring fingers are interdigitated with the second spring fingers. The forward and aft rings the mounting flange and the spring fingers are all part of a single monolithic component.
