Function
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.
Features
- Asymmetrical, double acting rotary seal, designed with interference on the OD which provides a good static fit in the groove.
- Additional sealing edge on the OD for better static sealing.
- Dynamic sealing on the ID.
- Excellent static and dynamic sealing performance.
- Low friction.
Application
Slow moving shafts, pivoting movements, revolving distributors, swivel joints.
Universal rotary seal for minor work loads.
Max. pressure 160 bar, max. speed 0.2 m/s.
Installation
Snap-in installation.
