Rod seal RSD 20x30x7 PU [2ERSD103]

The U Ring RSD 20x30x7 PU [2ERSD103] 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. Its construction includes two lips, which are pressed against the cooperating surface thanks to the elasticity of the material. An additional lip stabilizes the seal and protects against external contaminants. The design prevents the stick-slip effect and supports the operation of the seal at low temperatures. The technical data of the U Ring RSD 20x30x7 PU [2ERSD103] are:

• 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 U Ring RSD 20x30x7 PU [2ERSD103] is a high-specification product that meets the requirements of the most demanding hydraulic applications.
