Rotary Seal XSR08
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 inside sealing, designed with interference of the O-Ring on the OD and no interference of the PTFE glide ring on the ID.
- Excellent sealing performance at low speeds with high pressure.
- No tendency to “stick-slip” effect.
- Low break-away load after long standstills.
- Good gap extrusion resistance.
