RS117R

Technical drawing of a mechanical component with dimensions and angles, including labeled radius, thickness, and diameters, with a rounded, burr-free edge design.

Asymmetrical Rod Seal with backup ring.
Suitable for large extrusion gaps and for higher pressure ranges.
With additional sealing or stabilising lip.
Use in telescopic cylinders and special installation spaces.

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.
