Abstract
A turbomachine having a rotor that extends along a rotational axis and a radial bearing in which the rotor is radially mounted on a radial bearing point. In the axial region of the radial bearing point, the rotor has a hollow chamber annularly located in the circumferential direction in the region of the outer 20% of the diameter of the radial bearing point and which is thermally insulating between a radially inner core region of the rotor in the region of the radial bearing point and the radial outer region of the rotor in the region of the radial bearing point. A first shaft end of the rotor protrudes from the axial center of the radial bearing point by a projection over the radial bearing point, wherein a first quotient QLO of the projection OVH divided by the total length TLE of the rotor QLO=OVH/TLE>0.15.
