We have developed a non-contacting type centrifugal blood pump with hydrodynamic bearings. The purpose of this study is geometric optimization for step thrust bearings to achieve low hemolysis. Hydrodynamic axial loads generated in beating gap were obtained through numerical analysis based on Reynolds equation in lubrication and were compared vith the measured loads with electronic balance. As a result, hydrodynamic axial loads was the largest when the step length was designed to be 66.7% of the vane length.
