1. An aerodynamic bearing for the axial and radial mounting of a shaft extending along a rotation axis for a turbo compressor, the aerodynamic bearing comprising:
two annular axial bearing disks and a hollow cylindrical radial bearing bush,
wherein the two axial bearing disks and the radial bearing bush are arranged concentrically to the rotation axis,
wherein the two axial bearing disks are spaced apart in the axial direction and form a cavity between them in the axial direction for receiving a shaft sleeve connected to the shaft,
wherein the two axial bearing disks each have an axial bearing surface facing the cavity for forming a respective axial gas cushion in a respective axial bearing gap between the respective axial bearing surface and the shaft sleeve for the axial mounting of the shaft,
wherein the radial bearing bush has a radial bearing surface radially inward for forming a radial gas cushion in a radial bearing gap between the radial bearing surface and the shaft for the radial mounting of the shaft,
and wherein the radial bearing bush is formed integrally and/or materially with one of the axial bearing disks as a combination bearing bush.
