Ce dispositif comprend un bras support (7) qui se déplace à l'aide d'un mécanisme d'entraînement dans une direction de déplacement par rapport au châssis (5) du dispositif de positionnement et qui s'étend perpendiculairement à la direction de déplacement. Le bras support (7) est monté mobile dans la direction de déplacement par un palier fixe (8) dans la zone d'une extrémité et par un palier support (9) mobile dans la zone de l'extrémité opposée. Le bras support (7) s'appuie sur une surface de guidage (14) du palier support (9), cette surface étant parallèle à la direction de déplacement et oblique par rapport à une surface fixée par la direction de déplacement et l'axe longitudinal du bras support (7). Et un moyen génère une force agissant sur le bras support (7), de telle façon que le bras support (7) soit sollicité sur les côtés du palier support (9) par une réaction de palier supplémentaire perpendiculairement à la surface de guidage (14) du palier support (9).
