method of charging dynamic - pressure bearing device with lubricating fluid . preparatorily , lubricating fluid is put into a vacuum chamber and the chamber is vacuum - evacuated to subject the lubricating fluid to a degassing process . an appropriate quantity of fluid is dispensed in one end of the bearing gap , with the bearing device having been placed in a reduced - pressure ambient . in carrying out the dispensation , the pressure of the ambient is adjusted so as to be higher than the pressure during the degassing process . the method in this way prevents the lubricating fluid from frothing when it is being dispensed , and makes it possible to charge dynamic - pressure bearing devices with lubricating fluid without soiling the bearing - device surfaces with splashes or other contaminants .
