Abstract
A gas turbine engine has a bearing housing concentrically disposed inside the inner case of a turbine exhaust case (TEC). The bearing housing has a tubular body and an outer flange projecting from a radially outer surface of the tubular body. The outer flange has an axially extending segment spaced from the radially outer surface of the tubular body by an annular gap. The axially extending segment has a radially outer end surface connectable, such as by welding, to a mating flange projecting radially inwardly from the inner case of the TEC.
