To provide a bearing rigidity evaluation apparatus, capable of accurately determining the quality of the bearing rigidity of a bearing with an outer ring shape having right-to-left asymmetry and vertical asymmetry.
The bearing rigidity evaluation apparatus for evaluating the bearing rigidity of a bearing such as a double row bearing and a combinational bearing to which a pre-load has been applied includes an outer-ring-fixing device for fixing the outer ring of the bearing, a shaking device for providing vibrations of a prescribed frequency in an axial direction for either the inner ring of the bearing or a shaft fitted in the inner ring, and a vibration detector for detecting vibrations at the position of the axial center of either the inner ring or the shaft fitted in the inner ring.
