ABSTRACT:
The difference between a revolution period of larger diameter-side balls and a revolution period of smaller diameter-side balls is smaller as compared with a conventional bearing. The relation, (β−10)≦α<β, is established, where α(°) represents a contact angle of the larger diameter-side ball, and β(°) represents a contact angle of the smaller diameter-side ball.
