Abstract
Degradation degree of a bearing mechanism is diagnosed. A diagnosis apparatus includes: an acquisition unit that acquires measurement data relating to vibrations corresponding to a rotation of a bearing mechanism including rolling elements between an outer ring and an inner ring; an extraction unit that extracts a feature amount from a result of performing a frequency analysis on the measurement data; an estimation unit that estimates a size of a scratch generated on the outer ring or the inner ring based on a predetermined relationship between a change of the feature amount and a size of a scratch generated on the outer ring or the inner ring, and based on the feature amount extracted by the extraction unit; and an output unit that outputs an estimation result of the estimation unit.
