PURPOSE: To provide the multiple bearing withstanding high revolution by fitting a plurality of individually rotating rings in the circumference of a shaft coaxially.

CONSTITUTION: The multiple bearing is equipped with an inner race 1, an intermediate race, and with an outer race 3, and the outer race 3 acts as a support frame for the bearing. A plurality of spherical balls 4 are interposed between the inner race 1 and the intermediate race 2 so as to be formed into a rolling bearing. Besides, a plurality of spherical balls are also interposed between the intermediate race 2 and the outer race 3 so as to be formed into a rolling bearing. Therefore, these components are so constituted as to be the rolling bearing of a double structure.
