PROBLEM TO BE SOLVED: To provide a shaft alignment system for a reciprocating shaft having high shaft aligning accuracy and requiring less working man-hours and to provide its method. SOLUTION: A shaft supporting member 3 in a laminated structure for supporting the shaft 2 via a spring 31 is positioned and held by a cylinder 61 as an original point setting means and an X-stage 62 as a shaft supporting member moving means and a Y-stage, not illustrated, and it is pressed and held into the state of being fixed with screwing by a pressing mechanism 4. Then, the shaft 2 is shifted and released from a balance position for free motion. The motion is detected by a position detecting sensor 71 and its output is analyzed by a vibration analyzer 72 to determine the contact or not of the shaft 2 with a shaft insertion portion 11. Depending on the determination result, the shaft supporting member 3 is re-located and the shaft 2 is positioned. Acoustic emission can be utilized for determining the contact or not.
