Function

Rod seals are designed to seal the pressurized hydraulic fluid against the atmosphere or between two pressurized spaces.

 

 

 

 

Features

  •  Asymmetrical, single acting rod seal for hydraulic applications, designed with interference on the OD which provides a good static fit in the groove.
  •  Shortened sealing lip decreases contact area to the sealing surface thus resulting in reduced friction.
  •  Use in applications with lubricated air is possible.
  •  Small and compact housings possible.
  •  Useable for long stroke lengths.
  •  Negligible tendency to “stick-slip”, small break-away loads after long standstill.
