Abstract: The present disclosure provides a rolling-bearing replacement-timing prediction device and method enabling a more accurate replacement-timing prediction. A frequency spectrum of vibration data indicating vibration of a rolling bearing is determined for every sampling period and is stored in association with the sampling period into a storage unit. A specific peak not appearing during a normal state is detected from the frequency spectrum within a first frequency range including a theoretical frequency at which a peak occurs during an abnormality. When the specific peak is detected, a specific peak is detected as a re-detection specific peak within a second frequency range, which includes the specific peak and is smaller than the first frequency range, from at least one frequency spectrum stored in the storage unit prior to this sampling period, and the replacement timing of the rolling bearing is predicted based on the specific peak and the re-detection specific peak.
