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.
