Dynamic Slide Ring Double Acting:

Dynamic seal type with rectangular cross-section. The outer corners against the bore have sharp edges with improved scraping performance.
The disadvantage of the profile is increased risk of extrusion of the sharp corners that could eventually result in a leakage. Notches are present on both axial sides of the seal make it possible for the seal to be activated by internal hydraulic pressure this improves performance when the seal is subject to changing pressure from side to side.

  • Low stick-slip, (minimum static and dynamic friction)
  • Long life
  • Groove to ISO 7425/1

Limitations on Use  
Operating pressure Up to 40 MPa (400 bar)
Velocity reciprocating to 15 m/s
Temperature -40 to +200 °C (depending on O-ring material)



Serie Number AF-505
