The failure of hydrostatic bearing arises due to several factors. The eccentric load of workbench is one of the important factors that directly affect the oil film thickness, oil film temperature field, oil cavity pressure field, and surface quality of the machined part. In order to better analyze the anti-eccentric load characteristics, a mathematical model of the hydrostatic bearing with double rectangular cavity is established, the oil cavity flow, oil cavity pressure and oil film thickness under high-speed heavy-load and eccentric load conditions are solved based on the hydrostatic lubrication theory and tribological principle, and the eccentric load characteristics are simulated and predicted. According to the prediction results, a hydrostatic bearing with tilting oil pad is proposed to improve the problem of lubricating performance degradation caused by eccentric load, and the effectiveness of the scheme is verified by experiments. The results show that the comprehensive lubrication performance under eccentric load condition is less than that of central load. If the eccentric moment is too large, it will lead to local tribological failure of hydrostatic bearing, and the hydrostatic bearing with a tilting oil pad can proposed to improve its comprehensive lubrication performance and the anti-eccentric capacity.
