Fibre reinforced NBR compact seal SM is double acting: Uses range from intermedi- ate to high stress. Larger tolerances are pos- sible due to radial prestress. Split extrusion avoided due to choice of material in combi- nation with NBR and fabric reinforcement on dynamic side. SM 32 : NBR reinforced fabric : up to approx. 25 MPa (250 bar) : reciprocating to 0,5 m/s : -30 to +110 °C Piston Seal Material Operating pressure Velocity Temperature Special Features: Three part composition consisting of rein- forced fabric-elastomer combination and POM slide rings. Assembly for single part piston possible Reduced friction characteristic due to fabric reinforcement. Resistant to galling. Good resistance of pressure and vibrations. Has a small total width. Also available in FPM material.
