<p>The invention relates to a centre open large rolling bearing (1) consisting of a single- or multi-piece outer ring (2) and inner ring (3) and rolling elements (10, 11, 12) arranged between them and rolling on tracks (4, 5, 6, 7, 8, 9), in which one ring (3/2) is designed to accommodate an ultrasonic probe and the other ring (2/3) has a coupling surface (19, 24, 25). To design such a bearing in such a way that simple and reliable ultrasonic measurement becomes possible, one or more revolving coupling surfaces (19, 24, 25) are arranged on one or more outer surfaces of the ring (2, 3) to be tested.</p> |
