Due to recent developments in the industry, the demand for high-precision and high-performance machines has been rapidly increasing, and research on bearings has also been actively pursued. In the case of bearings, it is one of the mechanical elements that stabilizes the rotor rotating at high speed and minimizes the friction loss to smooth the operation of the system. Type of bearing is a ball bearing and sliding bearings. In this study, the bearing is a sliding bearing, which supports the thrust load. The sliding bearing has many advantages such as high bearing capacity, long lifetime, absorbency and impact resistance, and low noise compared to conventional ball bearing, and is widely used throughout the industry, research on this is also under way. However, existing researches are lacking in research on pivoting of thrust bearings, so there are many different parts from actual industrial sites. Therefore, in order to establish the standard of the thrust bearing pivot design for the load applied in this study, we analyzed and experimented. Bearing operation characteristics for the pivot offset ratio were 60% offset pivot and 50% offset pivot, respectively. From the results of this experiment, it was found that the bearing pads satisfying the optimal temperature condition were 60% It would be best if the offset is introduced. In addition, the optimal pivot radius value for the load was analyzed by stress analysis and finite element analysis through the Herzian contact theory, and the data value of the optimum pivot radius was tabulated for easier and faster pivot design.
