      With this type of cylinder, a guide housing is fixed to the cylinder. Either a guide rod (BZF) or a wedge clamping element (BZK) is installed in this guide housing. It is possible to use the wedge clamping element to achieve very high clamping forces. The guide rod allows the cylinder to accept very high side forces.
      The Block Cylinder serves as the drive unit, offering many additional options.
