Manufacturer's code: 2ERSD427 Material: Polyurethane (PU) Product description: The U Ring RSD 55x65x7 PU is a double-lip ring made of C0 polyurethane (based on polyester-caprolactam), designed for use in hydraulic cylinders. Both lips are pressed against the cooperating surface thanks 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. Technical data:

• 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
