RS205

  • Asymmetrical pneumatic rod seal.

  • Material adaptation possibilities for various applications.

  • Suitable for oiled ad dry pneumatic applications.

  • Special sealing lip contour for initial lubrication for stick-slip free operation.

Material and Application Parameters

²Pressure Values as a function of the hap dimension. The specified application parameters are generally valid values and must not be used simultaneously with the application. An order can be placed by specifying the profile type, material and specified housing design dimensions.
