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
c:> Asymmetrical, double acting rotary seal for outside sealing, designed with interference of the O-Ring on the ID and no interference of the PTFE glide ring on the OD.
c:> Excellent sealing performance at low speeds with high pressure.
c:> No tendency to “stick-slip” effect.
c:> Low break-away load after long standstills.
c:> Good gap extrusion resistance.
Application
Slow moving shafts, pivoting movements, revolving distributors, swivel joints. Max. pressure 350 bar, max. speed 0.4 m/s.
Installation
Snap-in installation.
Attention: PTFE glide rings need calibration after installation!
