On shock wave position in the clearance of externally pressurized circular thrust gas bearing, though visualization example by the schlieren method has been observed, it does not seem to find the example of visualizing the density distribution by the Mach-Zehnder interferometer with shock wave. In this study, the density distribution of externally pressurized circular thrust gas bearing has been visualized by the Mach-Zehnder interferometer.
