Description
Function
Rod seals are designed to seal the pressurized hydraulic fluid against the atmosphere, preventing leakage and pollution of the environment.
Features
- Asymmetrical, single acting rod seal, designed with interference on the OD which provides a good static fit in the groove.
- Dynamic sealing lip shorter than static lip to avoid drag pressure.
- Excellent static and dynamic sealing performance.
- Useable for long stroke lengths.
- Negligible tendency to “stick-slip” effect above a speed of 0.15 m/s.
For lower speeds the dynamic lip should be redesigned (shorter, stiffer).
Application
- Reciprocation rods in hydraulic cylinders, plungers.
- Universal rod seal for small extrusion gaps and minor load impacts.
- Also used as secondary seal in combination with RS09 (PTFE + O-Ring energizer).
- Max. pressure 400 bar, max. speed 0.5 m/s.
