The work presents the study of dynamics of heavy impeller rotor and failure diagnostics of tilting-pad journal bearings. The started rubbing process in the bearings at resonance and increased rubbing phenomenon in both bearings by measurement of radial gaps, were identified experimentally in situ. The rotational speed was established when gravitational force became dominant compared to rotor gyroscopic force. Rotating system model was designed, simulated and verified.
