See full text

A bearing support structure is provided in a gas turbine engine with a support structure mounted to the outer casing of the engine, and the structure defines an annular seat concentric with a rotating shaft. A cylindrical solid sleeve is seated in the annular seat so formed and extends axially therefrom in a cantilever manner and is provided with an outer bearing raceway for roller bearings, the outer raceway being constructed in out-of-round such that when the bearing structure is inserted in the outer raceway, it will assume a circular configuration providing a load on the roller bearings.
