In-house cross-speed bearing vibration measurements for bearing diagnosis

This dataset contains in-house bearing vibration measurements acquired on a laboratory bearing fault test rig for cross-speed diagnosis. Five bearing health states are included: healthy, inner-race fault, outer-race fault, ball fault, and cage fault. Vibration measurements were collected at 1000, 1500, and 2000 r/min using a sampling frequency of 25.6 kHz. Each record contains 80128 samples. The dataset is used as an independent laboratory validation set for cross-speed bearing diagnosis under operating-condition shifts.
