Apparatus for supporting shaft

A rotating shaft support device is disclosed. A rotating shaft support device for rotatably supporting a rotating shaft, comprising: a base, a supporting roller installed on the base, and a garden-shaped outer circumferential surface rotatably supported on the supporting roller, the rotating shaft penetrating hole passing through the central portion thereof. Ring frame having a rotating shaft supporting device including a rotation center alignment member for one side is installed in the ring frame and the other side is fixed to the rotating shaft so that the center of rotation and the center of rotation of the ring shaft coincide, when the rotating shaft is rotated Vibration can be prevented from occurring due to the eccentricity and uneven surface of the rotating shaft. Rotary shaft, dustproof, machining
