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, designed with interference on the ID which provides a good static fit in the groove.

c:>  Additional sealing edge on the ID for better static sealing.

c:>  Dynamic sealing on the OD.

c:>  Excellent static and dynamic sealing performance.

c:>  Low   friction.


Slow moving shafts, pivoting movements, revolving distributors, swivel joints. Universal rotary seal for minor work loads.
