Method, according to the eddy current method, for checking damage on the surface of round, e.g., ball-shaped, metal objects, whereby a similar object is supported and made to rotate around at least one axis while an electronic contact-free scanner or sensor is aimed at the surface of the object, characterized by the fact that the round object is placed on a fixed support and a gaseous medium, e.g., air is blown against the object in such manner that between the support and the object a gas or air layer is formed which carries the object, and the object is made to rotate by the gas or air flow.
