ABSTRACT:
A technique for determining properties of a bearing assembly in use involves using an eddy current probe for detecting changes in material density within a raceway of the bearing assembly. A field of detection of the eddy current probe enters the bearing raceway intermediate races that define the raceway, and as such the detection is of the bearing elements, and not deflections in a wall that defines the raceway.
