Rotor of a gas turbine

A rotor for a gas turbine, comprising:

• a compressor-side section;
• a turbine-side section;
• a plurality of individual compressor-side rotor components
• a plurality of individual turbine-side rotor components;
• a tie-bolt;
• and
• a support wheel,
• wherein the plurality of individual compressor-side and turbine-side rotor components are pressed to each other using a tie-bolt and assembled to form a rotor unit,
• wherein for each tie-bolt provided, each rotor component has a tie-bolt opening which extends in an axial direction of the rotor,
• wherein the tie-bolt extends through the respective tie-bolt opening leaving a space between the tie-bolt and the respective rotor component,
• wherein a wheel support is arranged as a rotor component between the turbine-side rotor section and the compressor-side rotor section and radially supports the tie-bolt.
