ABSTRACT:
A moving element which forms a sliding carriage comprises a housing with several pairs of guiding balls supported therein, which balls are arranged for contacting and rolling on guiding surfaces of a guide means. Each guiding ball is supported by a roller bearing and is rotatable around the axis of said bearing when travelling along a guiding surface contacting the same along a little circle of its surface. The guiding balls are positioned in groups, each group of balls forming a set to provide a form-locked support transversely to the guiding direction. One ball of each set is elastically biased against the respective guiding surface. Therefore the roller bearing of said ball is mounted axially displaceable and is supported by a spring washer against an adjusting screw in said housing. Thereby a compensation of play is achieved without making necessary a precise machining of the guide.
