K31: u seal single acting seal
Material Speed m/s temperature °C pressure Mpa
Nbr+PU+Pom 0,5 -30 +100 63
  • K31


K31 seal consists of three parts: the seal part in PU (Polyurethane), the part in NBR and the anti-extrusion ring in POM. 
This seal can work at high pressures thanks both to the PU part and to the rubber part between the two lips which afford the sealing at low pressure. The anti-extrusion back-up ring in acetal resin guarantees a better resistance to extrusion.The L profile of the sealing part in PU ensures a further protection against the entry of dirt particles.
 
GENERAL FEATURES: 
- Ease of mounting
- High abrasion resistance 
- High extrusion resistance 
- Low deformation value 
 
FIELD OF APPLICATIONS 
Mining equipment, steel mills, metal injection machines, scrap shears, hydraulic marine cranes and mobile hydraulics.
