The　objective　of　this　work　is　to　study　the　characteristics　of　the　hydrostatic　bearing　with　nanolubricant.　To　investigate　the　effect　of　nanoparticle　additives　on　the　performance　of　hydrostatic　bearings,　a　coupled　heat　transfer　finite-element　model　of　the　hydrostatic　bearing　is　developed,　and　the　results　of　the　static　and　dynamic　performance　of　the　hydrostatic　bearing　with　lubricant　and　nanolubricant　are　evaluated　based　on　computational　fluid　dynamics　methods　at　different　eccentricity　ratios.　The　results　show　that　the　rotation　error　of　the　bearing-rotor　system　is　reduced　by　using　nanolubricant　at　a　high　eccentricity　ratio.
