Parker ZX piston seal combination
ZX piston seal is a double-acting piston seal. It consists of a rubber sealing element, two retaining rings and two angle guide ring.
This seal assembly advantages:
● itself only a small space can be guided seals and sealing.
● suitable for mineral oils, HFA, HFB, HFC solution (maximum temperature + 60 ° C).
● Easy installation without expensive accessories.
● simple overall piston structure.
● in accordance with ISO6547 standard groove design.
● Series with Light or heavy series to adapt to various conditions of work and make full use of the cylinder material.
Cylinder sealing applications are restricted conditions of work. For poor working conditions, it is not recommended to use all the selected parameters in the table (see below). On the other hand, when used at lower temperatures may exceed these values.
If the special requirements (pressure, temperature, speed, etc.), please consult our service department in order to recommend the right materials and structures.
1. Material:
Rubber element: NBR material Shore A hardness of about 80.
Collar: polyester elastomer (W5035).
Angle guide ring: filled polyamide (W5019 / W5020)
For high temperature and chemical resistance of the working conditions, it is recommended to use the company FKM material. If the special requirements (temperature, velocity, for water, HFA solution, HFB and other liquid media), please contact our service department in order to recommend the right materials and structures.
2. Application:
Working pressure:
The maximum allowable pressure temperature
60 ° C 400bar
80 ° C 315bar
100 ° C 250bar
Operating temperature: -30 to + 100 ° C HFA, HFB, HFC fluid, maximum temperature 60 ° C
Surface speed: ≤0.5m / s
If these cylinders manufacturing dimensions (including tolerances) in the range of mechanical stress (eccentric and expansion) to keep as close as possible, the parameters are valid. The seal assembly for controlling industrial and mobile equipment hydraulic cylinder, the support cylinder, the cylinder, double-acting piston presses.
3. Install:
In the seal mounting region sharp edges and burrs should be removed. When installing the seal, please note that the various elements of the natural order: First install one of the miter guide ring. Carefully guide retainer ring and the contact point (opening) do not exactly in a row, and staggered according to the order of installation.
