Multiple hydraulic chambers that are located within the inner race-outer race interface of a spherical bearing are individually pressure controlled to maintain lateral, or axial, centering of the inner race relatively to the outer race. Pressure control is provided by a mechanical/hydraulic spool valve, one associated with each chamber, which senses the depth of the clearance space between the inner and outer races and pressurizes or vents the associated chamber to maintain the inner race centered in the outer race in a forcing manner. An internal actuation system for the hydraulic bearing is also provided comprising multiple cavities that are displaced both longitudinally and angularly with respect to the centering hydraulic chambers.
