• Seal size: 78x86x8
• Manufacturer's code: 2ERSD597
• Material: C0 Polyurethane

Technical data:

• Working pressure: up to 400 bar (at 60°C)
• Linear speed: up to 0.5 m/s
• Temperature range: from -35°C to +100°C (temporarily up to 110°C)

• Material: C0 polyurethane with high abrasion resistance and low permanent deformation

The ring's design ensures that both lips are pressed against the cooperating surface due to the elasticity of the material. An additional lip stabilizes the seal and protects against external contamination. The design prevents the stick-slip effect and supports the seal's operation at low temperatures.
