ABSTRACT:
A spray painting nozzle designed as a spindle supporting a gas bearing and incorporating a stationary part and a part rotatably supported in relation thereto, which latter carries a rotatable spray painting cup and being adapted to be driven by a drive unit, whereby the spray painting cup is equipped with a supporting system comprising mutually plane-parallel bearing surfaces formed in the stationary and in the rotatable parts, and with a supply of a gaseous medium for causing a slot generated as an axial gas bearing therebetween, the rotatable part being radially guided by a magnetic force for centering the rotatable part in relation to the stationary part, the supporting system further being equipped with symmetrically provided holder magnets for limitation of the size of the slot, and where for supply of spray medium to the spray painting cup, there is provided a supply path extending through the plane of the gas bearing.
