XRB

The rod seal type Aston Seals XRB, used preferably for hydraulic joints and rotary joints, is composed of:

  • A dynamic seal element which assures exceptional low friction and high speed performance, as well as high compatibility with nearly all media due to the chemical resistance which exceeds that of all other thermoplastics and elastomers.
  • A standard size O-Ring with low permanent deformation as energizing component on the static side
  • Low static and dynamic friction
  • No tendency of stick-slip
  • Space-saving construction and simple groove design
  • High resistance against extrusion
  • High compatibility with nearly all fluids (with the right choice of O-Ring material)
  • High speed allowed
  • High temperature resistance
  • Can also work for single action
