Zusammenfassung:	A ball carriage includes a raceway including an engagement segment to urge balls into rolling engagement with an element that is movable relative to the ball carriage. The engagement segment defines an opening through which balls are to engage the element. The raceway includes a return segment including a curved surface to take balls out of engagement with the element. The engagement segment and the return segment share a raceway surface that runs a full length of the raceway to contain balls within the raceway. A ramp is positioned at a transition from the engagement segment to the return segment. The ramp rises from the raceway surface at the opening towards the return segment to guide balls out of engagement with the element and into the return segment.
