PROBLEM TO BE SOLVED: To provide an analyzer of rotation vibration signals of a rolling bearing, permitting easy obtaining of the shape errors of component parts from a bearing oscillation waveform, without high level knowledge regarding influence due to the shape errors of the component parts acting on oscillation of the rolling bearing, thus giving expectation for improvement in the quality of bearing manufacturing and improvement in the estimated accuracy in the diagnosis of bearing abnormality. SOLUTION: A measured signal input means 4 is provided for inputting a measured signal given, by measuring bearing oscillation due to a rotation swing of the rolling bearing 2. A condition storage means 5 is provided for storing operation conditions, internal specifications and measurement conditions of the rolling bearing 2. An analysis means 7 is provided for computing component part shape errors as one among the values of swelling of an inner ring raceway surface of the rolling bearing 2, swelling of an outer ring raceway surface, swelling of a rolling element, and the magnitude of the mutual of difference in the diameter of the rolling element from the measured signal input in the measured signal input means 4 in accordance with predetermined analysis rules 6, in response to the operating conditions, internal specifications and measurement conditions stored in the condition storage means 5.
