Construction

One of the main equipment features of the Hunger casting cylinders is the integrated anti-rotation protection over the entire stroke, which is available for single and double acting cylinders. The extremely stiff piston rod guidance in the cylinder head ensure a constant guiding length over the stroke. For the increase of the bending and anti-rotation resistance, the head guidance is additionally being supported by a piston guidance. Furthermore, low friction seal and guiding elements of plastic compound-construction ensure a stick-slip-free movement.
