PARKER OR type (double acting) PTFE rotary seal

1.OR type rotary seal introduced
Rotary actuator manufacturers are more like a simple sealing structure. This can be sealed with an inner diameter of OR-type seal is achieved. They consist of wear-resistant, low-friction sliding ring and nitrile rubber O-rings.

OR-shaped rotary seals are mainly used alternately pressure from one side of the seal to the other side of the place, such as a rotary spindle track, swivel joints, hose reel scratch wheel, as well as for hydraulic machines. If this seal is used to seal the ends, preferably with a dust ring to close this structure.

Considering the special working conditions, OR rotary seal opened one or two annular lubrication grooves.

This sealing structure of advantages:

● short installation length.

● Start small friction, no stick-slip phenomenon, even at low speeds can ensure smooth movement.

● low wear.

● anti-extrusion.

● high temperatures.

● Since the rod seals have a wide range of chemical compatibility, and are available in a variety of O-ring material, it is compatible with almost all media.

● provide maximum diameter of 2500mm products.

2. Standard materials:

Slide ring: Polon ® 033, a modified PTFE + 25% carbon.

O-ring: N0674, Shore hardness of about 70 NBR rubber.

If the special requirements (pressure, temperature, speed, etc.), please contact our advisory service department, they will refer you to the appropriate materials and structures.

3. Application:

Working pressure: ≤300bar

Working temperature: -30 to + 100 ° C *

Surface speed: ≤1.0m / s

For rotational motion, is recommended in the p • V≤40 range.

Temperature beyond the standard operating conditions, please consult the appropriate Parker O-ring material.

Please seal this guide together with the use of (F3: Closed, Z type).

4. Installation:

Less than 30mm rod diameter required to open trenches.
