Rod seal RSD 20x28x7 PU [2ERSD771]

The RSD type rod seal from the Italian manufacturer Artic Seals 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 operation of the seal at low temperatures.
