ABSTRACT:
A bearing vibration measuring apparatus is an apparatus of measuring vibration of a bearing. The bearing vibration measuring apparatus detects a vibration component generated from the bearing in a state of pressing one of an inner ring and an outer ring of the bearing in an axial direction while relatively rotating other of the inner ring and the outer ring to detect a defect of the bearing based on the vibration component. The bearing vibration measuring apparatus includes a driving mechanism elongated and contracted for inclining the inner ring or the outer ring.
