The utility model greatly improves the efficiency and accuracy of bearing assembly and reduces manual operations.

[0030] according to Figure 3 and Figure 6 As shown, a movable rod 15 is also provided on the rotating shaft 13, and a driving rod 16 is provided at one end of the ball-moving cylinder 14. A through hole 17 is provided on the driving rod 16. The function of the through hole 17 is to allow the movable rod 15 to pass therethrough and rotate a certain angle.
