In　this　paper,　a　water-lubricated　hybrid　with　four　stepped　recess　supporting　a　high-speed　spindle　system　is　studied.　A　two-dimension　finite　element　method　considering　turbulence　effect　and　the　relationship　between　temperature　and　viscosity　is　developed　to　solve　the　Reynolds　equation　to　obtain　different　bearing　performance.　This　paper　mainly　discusses　the　influence　of　the　water　supply　pressure,　rotating　speed,　and　load　carrying　capacity　on　the　power　loss,　friction　coefficient　and　temperature.　The　results　presented　in　this　study　are　expected　to　be　useful　for　the　design　of　water-lubricated　hybrid　bearing　used　to　support　high-speed　spindles.　©　(2013)　Trans　Tech　Publications,　Switzerland.
