Parker CR-type piston rod seal combination
  CR-type piston rod seal consists of a combination of PTFE rod seal and an O-ring composition, used in hydraulic cylinder piston rod and plunger.

 CR-type piston rod seal in the dynamic combination of occasions as a substitute for the O-ring to improve sealing performance and wear resistance.

advantage:

● minimum friction starting and movement, even at low speeds but also to ensure smooth movement, no creeping phenomenon.

● low wear.

● anti-extrusion.

● high temperatures.

● Since the seal ring has a high resistance to chemical corrosion media features, by selecting the O-ring of different materials, CR seals can be applied to almost all media.

● it can be used in existing O-Ring grooves.

● can provide up to a diameter of 2500mm products.

Note: For special applications, such as heavy load or light load, you can choose a non-standard section. In this case, select another section instead of the standard cross-section, for example: the above example, with a "C" or "E" section replace "D" section.

Applications:

Working pressure: ≤350bar

Working temperature: -30 ℃ to + 100 ℃ *

Surface speed: ≤4m / s

* When the standard deviation of temperature, please consult the appropriate Parker O-rings. Please refer to the 17 O-ring material designator form.

Please use this seal together with the guide strips (such as F3).
