Date Mar. 11, 1999A mounting assembly for a machine tool carriage is driven by linear motors (4) at each end guided on fixed parallel rails running parallel to one another. At each end the bridge of the carriage has bearing plates seated on the linear motor friction plates against which it is urged by spring force. As each end of the bridge has a mounting bolt extending through the bridge and bear plate and is pivotably seated in a guide aperture in the carrier. On at least one end of the bridge, the guide bolt aperture is elongated so that the bridge can pivot about the guide bolt at the other end.
