Abstract
A bearing system for reducing end clearance and axial vibrations includes a bearing housing and a bearing. The bearing is a thrust bearing and may be of any type, such as a flat thrust face, a taper land thrust bearing or a tilt pad thrust bearing. The bearing housing includes a cavity to hold the bearing. A fluid cavity is formed between the bearing and the bearing housing. At least one fluid passageway extends through the bearing housing to feed fluid to the fluid cavity. As fluid is introduced to the fluid cavity the pressure in the cavity moves the bearing outward, away from the bearing housing and towards the rotating thrust collar, reducing the clearance, or space, between the face of the bearing and the thrust collar, reducing or eliminating the vibrations.
