Hydrostatic thrust bearings have been widely adopted in machine tools. However, high level of temperature rise due to film shearing and hydraulic power of water pump leads to decrease of machining accuracy while operating at high speeds. This paper aims to investigate the temperature rise characteristics of a high-speed water-lubricated hydrostatic thrust bearing. Based on Newtonian law of viscosity, hydrostatic theory and first law of thermodynamic, considering the influence of pressure flow, shearing effect and centrifugal effect, the temperature rise of lubricating water has been deduced. The influence of rotational speed and eccentricity has been studied. Result shows that high-speed water-lubricated thrust bearing has good thermal performance.
