ABSTRACT:
A gas bearing part is provided, having gas supply means which open out into a recessed working surface which can be placed opposite a carrier plate to permit formation of a gas bearing relative to the carrier plate.
To obtain a friction-free movement, also with application of higher gas pressures the roughness of the working surface is less than 10 ru, preferably less than 4 ru. The working surface is further essentially conically recessed, whereby the tip of the conical recess is essentially in the centre of the surface.
