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.    
  • Peripheral grooves that enable the build up of a lubricant reservoir. 
  • No tendency to “stick-slip” effect.
  • Low break-away load after long standstills.
  • Good gap extrusion resistance.

 

 

Application

Slow moving shafts, pivoting movements, swivel or rotary joints. Used as seal between two pressurized spaces.

Max. pressure 350 bar, max. speed 0.4 m/s.

 

 

Installation

Snap-in installation.

Attention: PTFE glide rings need calibration after installation!
