    • A steady rest for centering a rotationally symmetrical workpiece in a housing, a guide slide axially adjustable in the housing, an actuator rod in a form-locking connection with the guide slide, and two control surfaces opposite one-another on the guide slide and configured so that the guide slide has a triangular cross-sectional contour, one tip pointing towards the workpiece and the opposite two tips point in toward the actuator rod, a middle steady rest arm in driving connection with the actuator rod, and two outer steady rest arms each on a side next to the middle steady rest arm, and mounted in a swivelling arrangement in the housing, the first free end of which is in contact with a control surface of the guide slide, the second free end gripping the workpiece, forming a three-point mounting with the middle steady rest arm adapted to hold the workpiece.
