Zurcon® Glyd Ring® D from Trelleborg Sealing Solutions gives the perfect combination of sealing performance and service life, through optimized contact pressure and minimized heat generated from friction. To achieve this, adequate friction is ensured with an innovative design that incorporates two special grooves in the D-shaped profile of the seal to sustain an oil film for sufficient lubrication of the seal against its counter surface.
The new Zurcon® Glyd Ring® D is manufactured from Zurcon® Z13 polyurethane material, which has been specially developed to cope with pressures up to 500 bar/ 7,250 psi at both sides of the seal and at temperatures up to +120 °C / +248 °F. The seal therefore gives long life, even under demanding conditions. Offering superb mechanical and elastic properties, the seal loses none of its resilience and can be used in cylinders with lower quality inner walls.
Alberto Livi, Product Manager for the seal at Trelleborg Sealing Solutions, says: “In the latest more powerful hydraulic applications, high pressure is combined with elevated temperatures. The new Zurcon® 13 polyurethane material used in Zurcon® Glyd Ring® D is specially developed to cope with this combination. That’s why we can say that Zurcon® Glyd Ring® D is truly ‘cool under pressure’ and that with it we can offer a seal that has a long life, even under unforgiving conditions.”
Core industrial applications for Zurcon® Z13 Glyd Ring® D include construction machinery, earthmoving equipment, mobile cranes, forklift trucks and any other solutions involving mobile hydraulics. The seal offers superior resilience and good friction properties. It is compatible with hydraulic, mineral, synthetic and water-based fluids and with a hardness of 60 shore D offers outstanding wear resistance, excellent extrusion properties and hydrolysis resistance.
