Rotary Seal XSR03
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 for high pressures and low speeds, designed with interference on the OD which provides a good static fit in the groove.
- Dynamic sealing on the ID.
- Backup elements on the left and right side for maintaining the function also at large sealing gaps.
- Excellent static and dynamic sealing performance.
