To manufacture parts for a dynamic bearing with remarkable durability at a low cost while ensuring miniaturization and high performance.
This method of manufacturing the parts for the dynamic bearing has a machining process for machining a dynamic bearing part material into predetermined shape, and a surface treating process for forming the surface of the dynamic bearing part material machined into the predetermined shape in the machining process, into a predetermined surface state. The surface treating process has magnetic barrel polishing treatment wherein a fluid 300, magnetic media 400 serving as polishing media, and the dynamic bearing parts 33 which are polished bodies, are put in a container 100, and the magnetic media 400 are moved by the external moving magnetic field with magnets 201 fixed to a turntable 200, to polish the polished bodies.
