Accumulator loaded, high dynamic long stroke cylinders need a special taylor made sealing and bearing system to cope with extraordinary system loadings and operational speeds. Only highest quality engineering plastics, elastomers and PTFE-based compounds can guarantee low friction grades and stick slip free movements.

Special developed Hunger DFE components like friction reduced lip seal TRO-I can improve the reliability of the whole cylinder system remarkably. For these demanding applications piston rods often come with coatings consisting of carbides, oxides or stainless steel in order to improve service life under operation – Hunger seals can be adapted to these hard wearing surfaces
