The FKM rubber inner skeleton oil seal is composed of fluorine rubber, metal skeleton, and spiral tension spring. It is generally installed in an open groove.
After the oil seal is installed, under the clamping force generated by spring contraction, it can overcome the gap caused by shaft vibration and jumping during rotation,
so that the lip of the oil seal can tightly adhere to the surface of the shaft. When the oil seal is working, The oil seal lip and the surface of the rotating shaft form a sealing contact ring.
Under the action of oil pressure in the sealing chamber, lubricating oil seeps into a very thin oil film between the oil seal lip and the rotating shaft.
The oil film is affected by the surface tension of the oil, forming a (crescent surface) between the surface of the rotating shaft and the outer edge of the oil seal lip to prevent oil from overflowing,
thus playing a sealing role, On the other hand, it can also provide lubrication between the oil seal lip and the shaft surface, enhancing the sealing life.
It has the characteristics of good wear resistance, low friction, and wide application range. Function: Industrial rotating shaft and spindle sealing,
used to prevent lubricant leakage and the entry of external dust, mud, and water. Applicable temperature: -30~220 ℃ Working pressure: 20mpa
Speed: 30m Characteristics: 1. High temperature resistance 2. Corrosion resistance 3. Permanent deformation 4. Anti aging 1. High temperature resistance .
the FKM rubber has excellent high temperature resistance. It can work for a long time at 200-250 ℃, and can work for a short time at 300 ℃.
The tensile strength and hardness of fluororubber significantly decrease with increasing temperature.
The characteristic of changes in tensile strength and hardness is that below 150 degrees, it rapidly decreases with increasing temperature;
Between 150 and 260 degrees Celsius, the downward trend is slow as the temperature increases. 2. Corrosion resistance:
FKM rubber has excellent corrosion resistance. It has excellent stability for organic liquids, different fuel oils, and lubricants,
and good corrosion resistance to most organic acids, hydrocarbons, benzene, and toluene.
3. Compression permanent deformation performance: FKM rubber is used for sealing at high temperatures,
and compression deformation performance is the key to it. The wide application of Viton rubber is inseparable from its improvement in compression deformation.
The resistance of fluororubber to compression deformation has achieved significant results.
4. The performance of VITONA, which is resistant to climate aging and ozone, is still satisfactory after 10 years of natural storage.
In air with an ozone concentration of 0.01%, there was no significant cracking after 45 days of exposure. Specification:
FKM rubber inner skeleton oil seal, without special specifications and dimensions (outer diameter * inner diameter * height),
unit: mm, available in stock with a maximum outer diameter of 400mm.
