Method and arrangement for providing a turbine or compressor device having a rotor ( 1 ), that includes a first rotor section ( 2 ) having at least one disc-shaped or annular element ( 3 ) which has a multiplicity of blades ( 4 ) arranged in series on a circumferential path for guiding a gas flow, and a second, elongate rotor section ( 5 ) which projects at right-angles from the rotor disc ( 3 ) and which has a rotor shaft ( 6 ) connected to the rotor disc. A first and second bearing ( 8, 9 ) are fitted at a distance from one another along the rotor shaft ( 6 ), and the first bearing ( 8 ) is arranged closer to the rotor disc ( 3 ) than the second bearing ( 9 ). The bearing holder ( 25 ) of the first bearing ( 8 ) has a greater outside width than other than other components ( 9, 14, 15, 31 ) arranged on the rotor shaft ( 6 ) between the first bearing ( 8 ) and the free end of the rotor shaft ( 7 ).
