All information contained in our catalogue is released only for sexls usage and not valid for special applications. Given parameters such as maximum pressure, temperature, sliding speed, surface contact pressure and media are determined in laboratory conditions.

In case the operating parameters are requested at maximum level, these values may not be achieved.

For lastas best recommendation It is been recommended for the most part of the sealing elements applications and it has a very common use. The variation in the percentage of ACN changes the volume, gas permeability, elasticity and compression set of the compound used in mineral oils, grease and fuel.


Nitrile is very durable against aliphatic hydrocarbons i. PTFE material does have the lowest coefficient of friction. Due to the low friction coefficient and high wear resistance, it performs well on poorly lubricating conditions as well as high sliding speeds.

It has very good resistance to all chemicals except alkaline metals, high pressure-temperature chlorotriflour and basic flourines. Hardness and elasticity make the material to be used widely in hydraulic applications. Depending onto the application; Hydraulic cylinders are being used in mechanical applications where reciprocating forces and movements are needed.

Sealing element is one of the most important parts of the cylinders. The sealing elements are being installed into the respective groove with a preload.

Figure 1 shows the sealing element in free state, preload after the assembly of the seal and the free space needed in the housing. The sealing element is able to work in low pressures due to this preload.


Figure 2 shows the pressurized media filling into the groove and sealing element is expanded with this pressure. Table 1 shows the most common media used with the sealing elements. The viscosity of the media is one of the reasons of wear in the sealing elements.

Pressure and temperature change the viscosity of the media. The viscosity of the media increases with the pressure The Online Industrial Exhibition. Catalog excerpts All information contained in our kaxtas is released only for general usage and not valid for special applications.
