Background: Hydrostatic bearings possess the advantages of strong bearing capacity, good
stability, small friction coefficient, and long life. The performance of liquid hydrostatic bearings directly
affects the accuracy and efficiency of CNC machining equipment. The performance is conducive to the
development of CNC machine tools towards high speed and heavy load, so it is necessary to sort out and
summarize the existing research results.
Objective: This study summarizes the current development status of hydrostatic bearings and explains the
development trend of hydrostatic bearings.
Methods: According to the recently published journal articles and patents, the recent experimental research
on hydrostatic thrust bearings is summarized. This paper summarizes many factors that affect the
performance of hydrostatic bearings, and discusses the effect of various factors on hydrostatic bearings.
Finally, future research on hydrostatic bearings is also presented.
Results: The study discusses experimental methods, simulation processes, and experimental results.
Conclusion: Dynamic and static pressure effects can be produced by changing the structure of the oil
cavity of the hydrostatic bearing. This effect can make up for the static pressure loss. By improving the
theoretical formula and mathematical model and proposing a new simulation method, the accuracy of the
hydrostatic bearing simulation can be obtained; the future development trends of the hydrostatic bearing
have been proposed in this paper.
