Rotary seals are designed to seal the pressurized hydraulic fluid against the

atmosphere, preventing leakage and pollution of the environment or to transfer liquids and/or gases from a stationary part into or out of rotating machinery.





c:>  Asymmetrical, double acting rotary seal for high pressures and low speeds, designed with interference on the OD which provides a good static fit in the groove.

c:>  Dynamic sealing on the ID.

c:>  Backup elements on the left and right side for maintaining the function also at large sealing gaps.

c:>  Excellent static and dynamic sealing performance.




Slow moving shafts, pivoting movements, swivel or rotary joints. Used as seal between two pressurized spaces.

Max. pressure 400 bar, max. speed 0.2 m/s.




Snap-in installation.

Backup elements shall not be split!
