X- Ring Made of NBR /FKM

Product Description

We have CNC machines and cooperate with universities and research institutions and have rubber material research and development team.
We established long-term cooperative relations of technology talents with Qingdao University of Science & Technology, Hebei University of Technology, northwest Rubber Institute, each batch on employee training, improve the staff technical level and cultural structure, creating a number of business elites. It lays a solid foundation for the healthy development of the company.
X- type sealing ring is the most widely used in hydraulic and pneumatic transmission system. Is mainly used for mechanical components under static conditions to prevent the leakage of liquid and gaseous media. In some cases. O type sealing ring can used to make axial reciprocating motion and low speed rotary motion of the dynamic sealing element. According to the different conditions, were chosen different materials to adapt.
custom-made is available


Principle:
X-ring is its own double-acting seal with the ability of elastic sealing. Pre-compression by the initial installation produces a radial or axial contact stress and system pressure superposition to achieve the sealing function.
The superimposed sealing force increases as the system pressure increases. Under pressure, the star seal is like a fluid with a very high surface tension. The pressure can be evenly distributed to all the surface.

X-ring is widely used mainly for dynamic sealing,but its use by the constraints of  pressure and speed 

The application of dynamic sealing:
A piston, a piston rod, and a plunger for sealing the reciprocating motion.
A shaft or mandrel for sealing swing, rotation, or helical motion.

Static Seal Application:
Seal radially stationary parts such as sleeves, end caps, tubes.
Seal the axial stationary parts, such as flanges, cover and so on.

Operating parameters:
Dynamic seal:
Reciprocating motion: ≤ 5Mpa no file circle: ≤ 30Mpa use file ring.
Rotary movement: ≤ 5Mpa Use file ring.
Static seal: ≤ 5MPa No file ring: ≤ 40Mpa Use file ring.

Working speed:
Reciprocating motion: ≤ 0.5m / s.
Rotational motion: ≤ 2m / s.
Temperature range: (depending on material and media).

Usually used: -30 ºC ~ 110 ºC.
Special materials: -30 ºC ~ 200 ºC.
Rotary motion: -30 ºC ~ 80 ºC.
Media: By selecting different properties of the material, the basic time for all liquid, gas and chemical seal.

Dia. can be from 10mm to 2000mm
