PURPOSE:In a static pressure fluid thrust bearing to be used for a vertical ballance tester, to apply the rotary force on a rotary member to be supported by the bearing by making the fluid pocket eccentric thereby easily producing the force component perpendicular to the load direction. CONSTITUTION:After releasing the auxiliary table of a ballance tester and the main table 4, the pressure fluid is fed from the supporting point A of each segment 14 of a fluid thrust bearing 11 to a fluid pocket 15 arranged along the circumferential direction while shifted to the predetermined direction, and the main table 4 will rotate with slow speed because the horizontal force component of the pressure fluid will function in the circumferential direction of the main table 4 to provide the rotary force. At the position where the main table 4 has rotated by 180 deg., the main table 4 is secured to the auxiliary table through the function of a positioning pin 20. |
