A system and method for filling hydrodynamic bearings with fluid is disclosed. The fluid filling system 100 of the present invention includes a vacuum vessel 110 for receiving the hydrodynamic bearing 10 therein, a pump 111 hermetically connected to the vacuum vessel 110 and exhausting air from the vacuum vessel 110 to the outside, an ultrasonic generator 140 for generating vibrations in the vacuum vessel 110 , and a fluid dispenser 120 for dripping the fluid into the hydrodynamic bearing 10 . When air is exhausted from the vacuum vessel 110 to the atmosphere by the pump 111 , the hydrodynamic bearing 10 is vibrated by the ultrasonic generator 140 and air is exhausted from a micro-gap 13 between the shaft 11 and sleeve 12 of the bearing 10 to the atmosphere.
