A multicoordinate sensing measuring device is proposed in which a sensing lever ( 5 ) that is resiliently spring-pretensioned in a resting position in a housing ( 3 ) can be displaced along a measuring axis ( 7 ) and can be pivoted transversely to the measuring axis ( 7 ). A connecting piece ( 25 ) is guided in a movable manner in the direction of the measuring axis ( 7 ) on a guide surface ( 23 ) of the housing ( 3 ). The sensing lever carries along the connecting piece ( 25 ) via a linkage ( 31, 33 ) when the sensing arm ( 5 ) is displaced in the direction of the measuring axis ( 7 ) as well as when the sensing arm is deflected in the direction of the measuring axis ( 7 ). A measuring device ( 21 ) detects the position of the connecting piece ( 25 ) relative to the housing ( 3 ). The connecting piece ( 25 ) and the guide surfaces ( 23 ) form bearing surfaces for balls of the ball bearing arrangement ( 27 ) where the bearing surface of at least one of these components-connecting piece ( 25 ) and housing ( 3 )-can be elastically deflected transversely to the bearing surface and clamps the balls ( 65 ) free of play between the bearing surfaces. The connecting piece ( 25 ) or/and the housing ( 3 ) are made of aluminium or an aluminium alloy and are coated with a comparatively thin hard-anodized layer into which the balls ( 65 ) can wear a track groove. Such a sensing measuring device can be manufactured with relatively large manufacturing tolerances and is nevertheless able to guide the connecting piece ( 25 ) in a movable manner essentially free of play in the housing ( 3 ).
