RS103

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.
Sealing Element Preload Element Temperature (°C) Max. Sliding Speed (m/s) Maximum Pressure²
HPU Premium NBR 70 -30 - +100 0.5 400 bar (5800psi)
HPU Diet NBR 70 -20 - +100 0.5 400 bar (5800psi)
SLPU NBR 70 -20 - +100 0.7 400 bar (5800psi)
HPU Low Temperature MVQ 70 -50 - +110 0.5 400 bar (5800psi)

Standard Dimensions

¹The specified extrusion gap is valid up to 70°C, higher temperatures requre lower values.
