Since it absorbs this, it is possible to prevent an abnormal and excessive axial load from being generated in both bearings 2a and 2b. Then, even if an attempt is made to cause outer ring creep in which the other bearing 2b rotates in a direction opposite to the rotation direction of the shaft 1 due to a so-called outer ring rotation load,
The circumferential frictional force of the preload spring 6 prevents this. However, if there is a larger outer ring rotational load, the other bearing 2
In b, the outer ring creep is caused by the rotational force exceeding the frictional force, and the bearing is damaged.
