A gas friction pump includes stationary ( 6 ) and rotatable ( 5 ) pump-active elements secured on a rotor shaft ( 4 ) and forming with the rotor shaft components of the rotor, with the rotor shaft ( 4 ) being supported by two, spaced from each other, radial bearings ( 8, 9 ), of which one is located closer to the gravity center of the rotor than the other, and an axial bearing ( 16 ), and with the radial bearing ( 9 ), which is located closer to the gravity center of the rotor, being formed as a gas bearing, and another radial bearing ( 8 ) being formed as a non-gas bearing.
