category of profile

molded/standard/trade product or machined with minor design change.

 

double acting

 

area of application: pneumatic

  • rod seal e.g. for ISO cylinders.
  • media: lubricated air as well as dry air and oil-free air (after initial lubrication on assembly).

 

advantages

  • combination seal with minimal space requirements, which seals inwards  and wipes outwards.
  • the component needs no additional element (circlip) for axial fixing within the housing.
  • long service life.
  • robust design.

fitting & installation

careful fitting is a prerequisite  for the correct function of the seal. the combination seal A65 is pressed into the housing from outside. the bead on the outside diameter snaps into the circlip groove and fixes the seal in the housing.
