Rod Seal XSRS19A
Function:
Rotary seals are designed to seal the pressurized hydraulic fluid against the atmosphere or between two pressurized spaces.
Features:- Asymmetrical, single acting rotary seal with clamping flange.
- Preload effected through V-spring.
- Dynamic sealing lip shorter than static lip to avoid drag pressure.
- Excellent static and dynamic sealing performance.
- Useable for short and long stroke lengths.
- Low friction in dry running or poor lubrication conditions, no stick-slip effect.
