A bearing housing for a heavy rotor is made axially-nonsymmetrical so that the bearing chamber therein is shifted axially of the rotor shaft upon reversing the bearing housing. With a new rotor, the nonsymmetry positions the bearing chamber axially outwardly from the housing center. When necessary, the rotor shaft, by virtue of having successively increased diameters inwardly from its end, can be reworked by turning new surfaces thereon positioned axially inwardly from the original surfaces. The bearing housing is then reversed so that its nonsymmetry locates the bearing chamber inwardly from the housing center, to accommodate the new positions of the shaft surfaces.
