Abstract
A machine for testing a centrifugal load of a bearing including an outer race member, comprising a supporting frame including a sun ring, and a rotational main shaft. The rotational main shaft includes mounting portions for mounting the bearing to be tested. The mounting portions includes a mounting shaft for mounting the bearing to be tested and a supporting bracket for supporting the mounting shaft. The mounting shaft is arranged in the supporting bracket in parallel with the rotational main shaft in such a manner that a part of an outer peripheral surface of the outer race member is projected radially outwardly from the supporting bracket. The mounting shaft is journaled to a supporting bracket with a displacing margin in a radially outward direction to the rotational main shaft. An inner peripheral surface of the sun ring is used as a track to be rolled with the outer race members of the respective bearings to be tested. The bearings are rotated around the rotational shaft and around their own axes along the inner peripheral surface of the sun ring.
