THE SERVO DEVICE, FOR EXAMPLE A VORTEX AMPLIFIER OR A FLUID AMPLIFIER, COMMUNICATES WITH A PRESSURE SOURCE AND THE SPACING BETWEEN THE SHAFT AND THE BUSHING OF THE BEARING. ECCENTRIC ROTATION FOR THE SHAFT ACTIVATES THE DEVICE TO SELECTIVELY INCREASE AND DECREASE PRESSURE WITHIN THE SPACING TO COUNTERACT SHAFT DISPLACEMENT.
