The positioning arm (1) has two linear bearings to engage in two parallel guide tracks of a stator. The bearings (2)are anchored at the end to the arm. The arm, at the other end, has a displacement axis perpendicular to the direction of displacement and at an angle to the guide plane. The bearing is supported by the axis and the axis acts as an axis of rotation for the bearing. The bearing, which acts as a support roller (5)), is mounted with some play on the axis of rotation and is guided without any play on the guide track. |
