Rod seal RSD 20x28x5,8 PU [2ERSD788]

The U Ring RSD 20x28x5.8 PU [2ERSD788] is a double-lip sealing ring, made of C0 polyurethane by the renowned Italian manufacturer Artic Seals. It has been designed for use in hydraulic cylinders.

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)
• Hardness: 93 Shore A ±2
• Material: C0 polyurethane with high resistance to wear and low permanent deformation

The ring's design ensures that both lips are pressed against the cooperating surface, which is possible thanks to the elasticity of the material. An additional lip stabilizes the seal and protects it from external contaminants. As a result, the ring prevents the stick-slip effect and supports the seal's operation at low temperatures. The U Ring RSD 20x28x5.8 PU [2ERSD788] is a high-quality product that will meet the expectations of even the most demanding customers.
