Abstract
A linear guide comprising at least two stationarily supported guide bars, on which a guide block is mounted and which is longitudinally displaceable relative to the guide bars. The guide block is provided with a driving unit to generate a relative movement with respect to the guide bars, the driving unit comprising a pinion which meshes with the teeth of a toothed rack extending in parallel with the guide bars. The toothed rack is mounted only at its front and rear ends and is suspended in-between. A guiding element assigned to the pinion is mounted to the guide block so as to be displaceable in the longitudinal direction of the toothed rack on which it is supported in a form-locking manner. The guiding element engages over the toothed rack at the region opposite the mesh between the pinion and the teeth.
