RS124

Technical drawing of a mechanical component with annotations indicating dimensions, rounded and burr-free edges, including diameter measurements, length, and angles.

O-Ring supported PTFE sealing element, double acting.
Excellent frictional properties; for low and high speeds.
In combination with double lipped wiper RA211 or rod seal RS101.
Very good suitability for pressure surges.

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.
