The characteristic equatioins in which the inertia and compressibility of oil and the squeeze film effect are considered, are derived for a hydrostatic thrust bearing supporting a constant load and intermittently being supplied with pressurized oil as square wave form.Meanwhile, these characteristics are examined by experients, to confirm the relation between the mean value and its variations of the oil film thickness and the pressure wave frequencies.Conclusions of this study can be summarized as follows;(1) The mean value of the oil film thickness is functionally determined by the value and ratio of the supply pressure and the restriction coefficient of the choke, if the supply pressure is always higher than the balancing pressure.(2) The squeeze film effect evidently appears in low frequency region, but in high frequency region and with strong restriction effect it diminishes because of small variation of the oil film thickness.
