ABSTRACT:
A method and apparatus for inspecting the surface of a bearing ball is disclosed which includes a base (A) having a high friction non-abrasive base scanning surface (12). A holding device (B) includes a cone-shaped cup recess (14) in which a ball element (18) is received. Air is introduced through a passage (26) to relieve friction between the wall (16) of the recess and the ball element and facilitate rolling of the ball over the high friction base surface. The holding device is moved over the base scanning surface in a predetermined pattern (50) such that the entire surface of the ball element is inspected by an eddy current probe (C) which detects any surface defects.
