A structure and method of operation of a journal bearing is disclosed that minimizes contact of the shaft with the sleeve during start up and slow down of rotation of the shaft relative to the sleeve, or vice versa. The bearing assembly includes a gravitational load reduction mechanism with magnets disposed on the sleeve and on the shaft in alignment with one another. The magnet(s) on the shaft interacts with the magnet(s) disposed on the sleeve to provide a force against the pressure of the shaft towards the sleeve generated by gravity on the rotating component. The magnets enable centering of the rotating component within the stationary component during low rotation and non-rotation. This prevents rubbing of the rotating journal bearing component surfaces, e.g., sleeve, against the stationary journal bearing component, e.g., shaft, during assembly, ramp-up, and coast-down when the journal bearing fluid provides minimal or no bearing centering capability.
