Rod Seal, Single Acting, Hydraulics

Technical diagram of a blue mechanical part with a rectangular shape and an angled cut, labeled with a dimension 'H' indicating height.

Technical engineering drawing of a mechanical part with dimensions and angles, highlighting rounded and burr-free edges.

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

Asymmetrical Rod Seal
Tight fit on outer diameter for a stable hold in housing design
Good return characteristics, low stick-slip tendency
Secondary seal in combination with PTFE Rod Seal RS129

Diagram showing four types of motion: linear, static, oscillating, and screwing.

Brightened symbols: seal only for limited use.

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.
