FR

The Aston Seals FR type guide rings have been developed to substitute traditional bronze guides in hydraulic cylinders. They guide the rod or the piston and prevent metallic contact with the cylinder when radial forces act perpendicular to the direction of movement.
Chamfered edges prevent splintering of the material during assembly and make the installation into the groove easier.
The compound used for these guides is a medium viscosity glass  fibre reinforced acetal resin characterized by high strength, rigidity, hardness, impact resistance, resilience and excellent stability to high and low temperature.

  • Extended service life
  • Dimension suitable for both rod and piston
  • Excellent wear-resistance
  • Simple design of groove and assembly
  • Reduce vibrations
  • Low friction
  • Good resistance to loads
  • Good mechanical stability at high temperature
  • Easy installation without expensive auxiliaries
