Rod seal RSD 20x28x7 PU [2ERSD772]

The U RSD 20x28x7 PU [2ERSD772] is a double-lipped sealing ring, made from C0 polyurethane, designed for use in hydraulic cylinders. Manufactured by the renowned Italian manufacturer Artic Seals, it is characterized by high abrasion resistance and low permanent deformation.

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

The U RSD 20x28x7 PU [2ERSD772] is pressed against the cooperating surface thanks to the elasticity of the material, which ensures excellent sealing. An additional lip stabilizes the seal and protects against external contamination. The ring's design prevents the stick-slip effect and supports the seal's operation at low temperatures.
