Maximum force and minimum encumbrance for cylinders with piston seal. Unique construction design for cylinders with piston seal, an expression of the state of the art of Special Springs research. The KE series guarantees maximum service life and safe use thanks to the presence, as standard, of SKUDO (active protection against contaminants), OSAS (overstroke active safety), USAS (uncontrolled speed active safety) and OPAS (overpressure active safety) as standard. The only cylinders with piston seal connectable in system as standard, without the use of adapters, with encumbrance height saving of - 20 mm. Ideal for EASY MANIFOLD applications in the standard version
