A hydrostatic thrust bearing system characterized in that the hydrostatic bearings are axially movable and are held urged against the pressure plate in mutually opposite directions by hydraulic pressure created in a chamber associated with a respective bearing; and in that a servo valve is provided for co-action with an axial-position sensor for controlling the amount of hydraulic fluid fed to a respective chamber and also to control the hydraulic pressure acting on a respective bearing such as to take-up axial loads which vary in magnitude and direction.
