The complicated phenomena such as pressure depressions, shock waves and the negative pressure, are detected in the air flow with a large bearing clearance or high supply pressure in an externally pressurized gas-lubricated circular thrust bearing. The pressure depression, which decreases the bearing load capacity, is an undesirable phenomenon occurring in this gas bearing. The non-contacting suspension support of the object with the surfact processed by the lathe utilizing the negative pressure of this gas bearing is investigated experimentally, and is also discussed in this paper.
