The　internal　feedback　hydrostatic　bearing　features　a　distinctive　structural　design,　playing　a　pivotal　role　in　high-precision　machine　tools.　Its　performance　significantly　influences　the　improvement　of　machining　accuracy　and　stiffness.　In　this　study,　the　working　principle　of　the　internal　feedback　closed　hydrostatic　bearing　is　described,　the　equivalent　liquid　resistance　model　of　oil　circuit　considering　internal　flow　effect　is　established,　an　analysis　method　for　evaluating　the　support　performance　of　the　internal　feedback　hydrostatic　bearing　is　proposed,　flow　rate　correction　methods　are　proposed,　and　the　influence　of　load-carrying　capacity　and　flow　rate　due　to　inlet　pressure,　oil　film　thickness,　and　the　size　of　the　restrictor　is　discussed.　The　accuracy　of　the　method　is　verified　by　simulation,　and　insights　for　the　future　development　of　hydrostatic　bearings　are　provided.
