ABSTRACT:
A linear guiding apparatus comprises a rod having at least four guiding surfaces distributed over its periphery and extending in longitudinal direction of the rod. A carriage is arranged for a linear guided movement along the rod and has at least four rolls which engage a respective one of the guiding surfaces. Thus, the axis of each roll extends substantially in a direction perpendicular to the longitudinal axis of the rod, but is inclined with respect to a plane perpendicular to the respective guiding surface. In this way, the carriage is guided in axial direction of the rod by the rolls and is substantially free of torsion about the rod's longitudinal axis.
