here use SW simulation to create fixed clearance 4-point contact slewing bearing FEA model, ball model use springs model interation between raceways, only under gravity load the outer raceway displacement results on axial direction should be the clearance, and list connector force generate curve to see the clearance bearing will be get two point contact status only under gravity load. if SW can get the FEA model by adjust the stiffness and preload value of connectors?
