摘要：
The double-row ball bearing having a stationary shaft, a rotatable outer ring and balls between them is set in an inspection apparatus, so that the acoustic sound produced as the outer ring is rotated with the shaft inserted inside the balls is detected by a vibration pickup device to examine for the flaws on the surfaces of balls, shaft and outer ring.
