At rest it lies at the bottom of the clearance; once running, it climbs the hydrodynamic oil wedge and settles at an offset, eccentric position governed by speed, load, oil viscosity, and the forces fed in through the coupling. That equilibrium position is a direct, physical readout of the steady forces acting on the rotor. Vibration tells you how violently the shaft is shaking; the centerline tells you where it is being pushed. The two answer fundamentally different questions, and a complete diagnosis of a fluid-film machine needs both.<\/p>\n<h2>2.
