Special Features: Material : Operating pressure : Velocity : Temperature : NBR fibre reinforced S 20 to 30 MPa (200-300 bar) SG 20 to 45 MPa (200-450 bar) reciprocating to 0.5 m/s -30 to +110 °C Compact rod seals in the S and SG series are meant for a universal range of hydraulics applications. The rubber-fabric combination has been successfully used for many years, specifically for Bio Oil. Radially prestressed sealing edges guarantee good sealing even with impact pressures and high pressure fluctuations in addition to low pressure zones. S is manufacturd without back-up ring. The design SG with a back-up ring enhances operational security against split extrusion with high pressure surges. Lowest stick-slip tendency due to NBR fabric material combination Very good dynamic and static sealing Extrusion protection due to fabric reinforcement High pressure absorption possible due to separate thrust ring All dimensions (in SG as 40 mm onward) in closed grooves Rod Seal S+SG 86
