ABSTRACT:
A spindle for gas bearing of a rapidly rotating tool, in particular for aerostatic bearing arrangement of an open-end spinning rotor, including a spindle housing, a rotatable elongate shaft supported in the spindle housing in a radial direction of the shaft by a radial gas bearing element and an elongate extension rod. The rotor is coupled to the extension rod at a first end thereof. An extension rod bearing element is arranged at a region proximate the first end of the extension rod at which the rotor is attached. A first bearing clearance is defined between the radial bearing element and the shaft and a second bearing clearance is defined between the extension rod and the extension rod bearing element which is at least twice the first bearing clearance.
