Abstract
A bearing comprises two opposing ring and a single row of rolling balls accommodated in the raceways of each of the rings. At least one of the rings carries an ultrasonic scanning device for scanning specific areas of the other ring upon relative rotation of the rings. The ultrasonic scanning device is opposite the other ring next to the raceway of said ring, and is directed such that ultrasonic waves produced thereby impinge upon the raceway of the other ring sidewardly.
