A gas turbine engine comprising an annular casing and a bearing housing located concentrically with the casing and in spaced relation thereto. An annular exhaust gas duct is formed between the bearing housing and the outer annular casing. The bearing housing includes a pair of concentric spaced-apart rings connected in a cantilevered manner. The outer ring is supported to the outer casing by angularly, spaced-apart, radially extending support members, and the inner ring includes a cylindrical inner surface to which a concentric bearing support member is tightly fitted therein. The concentric bearing support member includes angularly, spaced-apart, support contact means tightly engaging the inner cylindrical surface of the inner ring while the remainder of the bearing support is out of radial contact with the inner ring of the housing to allow for minimum thermal conduction, yet stressed for relief in the tightly fitting support member within the bearing support housing.

In a gas turbine engine, an annular casing, a bearing housing located concentrically within the casing and in spaced relation thereto, the bearing housing including a pair of concentric spaced-apart rings connected in a cantilevered manner, the pair of rings including an outer ring supported directly by angularly spaced-apart, radially extending support members to the outer casing, and an inner ring including a cylindrical surface, a concentric bearing support member provided within said bearing housing and including angularly, equally spaced-apart support contact means tightly engaging said inner cylindrical surface of the inner ring of said bearing housing such that the inner ring may be subjected to circumferential distortions, thus absorbing the stresses of the fit between the bearing support and the inner ring.
