An electric machine contains a rotor which contains a first longitudinal section at the ambient air temperature and a second longitudinal section cooled at least partially to cryogenic temperature, a coolant inlet pipe extending into the second longitudinal section, wherein the inlet pipe is set at a distance from the rotor by a radial gap, wherein the inlet pipe in the first longitudinal section is mounted by at least two bearings, wherein the bearings are distributed on axial positions in such a way that upon action of a maximum radial force on the inlet pipe the pipe has a maximum deflection which is smaller than the radial gap. In a method for determining the axial positions, various batches of potential locations are chosen for the axial positions of the bearings, according to potential locations which has a minimum gap greater than zero.
