A compact, U‑profiled rod / gland seal that ensures sealing integrity when cylinder rod / gland deflections occur.
Lionsele U2 is a compact, U-profiled rod / gland seal manufactured in high-performance polyurethane. Its asymmetrical design ensures sealing integrity when cylinder rod / gland deflections occur.
In operation, the secondary sealing lip traps fluid behind the primary sealing lip and serves to increase lubrication. This prevents dry running, thus reducing the risk of stick-slip action. Seal life is significantly increased by the optimised fluid film conditions created beneath the primary sealing lip.
Moreover, the secondary sealing lip helps to exclude contamination from the primary sealing lip, further promoting seal life.
