RS103

Technical drawing of a mechanical component with dimensions labeled, including sections of rounded and burr-free edges, with various measurements and angles indicated.

The dimensions s + c are dependent on the respective seal type.

O-Ring supported asymmetrical rod seal.
Tight fit on outside diameter for stable hold in housing design
Excellent sealing effect due to the design.
Main application in the short-stroke range.

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.
