In the 1st Report, a simplified analysis for determining the pressure distribution, the load carrying capacity and the gas flow rate of an externally pressurized gas bearing have been presented by using the electrolytic tank analogy. In this report, an experimental result obtained by test bearings of various dimensions with multiple gas supply holes arranged circumferentially in one and two rows is described. 1. The pressure distribution and the flow rate of the test bearings under no load condition showed good agreement with the theoretical values described in the 1st Report. 2. The load carrying coefficient K_<LO> is independent of the number and the diameter of feed holes of the bearings when L/D and l/L are held constant. 3. Effects of L/D and l/L on load carrying coeficient K_<LO> are shown in Fig.14, and Fig.15 shows the ratio of K_<LO> to the theoretical value K_<Lth>. 4. The optimum condition to give minimum gas pumping power for the bearing is given. 5. The flow coefficients of restrictors for orifice compensation and inherent compensation have been obtained by experiments.
