It is still a current state in the research on the assembly accuracy by NRRO that doesn't synchronize with the rotation in the vibration of the small bearing built into the micro machine tool, though a highly accurate rotation is demanded from the driving shaft of the miniaturized machine tool. Then, in this research, I give the bearing the assembly error on purpose in consideration of an actual usage condition after the vibration experiment result of the bearing unit is considered. From the experiment results, it was able to be confirmed that the fc element total increased as the angle of gradient increased similarly when the unit was examined when the angle of gradient and parallel creep of center core was given to the bearing. Moreover, the fc and 2fc element changed chiefly, increased in a single purpose examination. However, when two bearings are combined, it is seen for all elements to change, to increase.
