Piston seals of the A series are designed to automatically exhibit very good sealing char acteristics and low friction at high stress val ues. Multiple lip type of sealing element design for the static as well as dynamic sides ensure guaranteed sealing even at low pressure. A 28 Material Operating pressure Velocity Temperature : modified NBR : up to 40 MPa (400 bar) : reciprocating to 0.5 m/s : -30 to +110 °C Piston Seal Special Features: Five part construction consisting of a wear resistant NBR sealing ring, two Hytrel elasto- mer support rings and two POM sliding rings Assembly in a split piston Special design for closed groove in piston is available Outstanding uptake of pressure surges and transverse loads No rotation of seal components depending on the design in combination with support rings Available for cylinder diameter up to 350 mm
