What is Journal Bearing Vibration about?

Rotor instability will occur when bearing pre-load is not sufficient to keep the rotating shaft in a stable position. Oil whirl can be easily recognized by its unusual vibration frequency which is generally on the order of 0.40X to 0.48X shaft RPM. At the first critical speed, instability may occur If vibration amplitudes reach 50% of the normal bearing clearance.
