A flexible housing is arranged along an axial centerline of a rotor shaft of a steam turbine. The flexible housing extends between an exhaust hood endcover and a seal end packing housing on a separate supporting standard. The flexible housing includes a top cover portion and a bottom cover portion with a flanged horizontal joint that permits removal and replacement without need to remove the exhaust hood cover and the rotor shaft. The flexible housing encloses the rotor shaft with a first cylindrical element and a second cylindrical element of a different radius joined with an thin member that flexes to absorb expansion and contraction of the turbine exhaust hood.
