Do you know its performance characteristics? Fluorine rubber skeleton oil seal!

Fluorine rubber Skeleton Oil Seal is a kind of polymer material, mainly a synthetic polymer elastomer with fluorine atoms attached to the C atom, a kind of synthetic rubber, but it is widely used, mainly in aviation, Chemical Industry, petroleum, automobile, etc. of the industrial sector.

What are the advantages of fluorine rubber skeleton Oil Seal?

As a Sealing material, it has excellent heat resistance, oxidation resistance, oil resistance and drug resistance. In terms of physical properties, fluororubber is a white or amber translucent sheet-like elastomer that is non-toxic, odorless, and non-spontaneous, but can be melted in low-molecular-weight ketones and lipids.

The skeleton oil Seal structure consists of three parts: the oil seal body, the reinforced skeleton and the self-tightening coil spring. The sealing body is divided into bottom, waist, cutting edge and sealing lip according to different parts. Usually, the inner diameter of the skeleton oil seal in the free state is smaller than the outer diameter, that is, it has a certain "interference amount".

Therefore, after the oil seal is installed on the oil seal seat and the shaft, the pressure of the oil seal edge and the contraction force of the self-tightening coil spring will produce a certain radial tightening force on the shaft. After a period of operation, the pressure will rapidly decrease or even disappear. , Therefore, adding a spring can compensate the self-tightening force of the oil seal at any time.

The function of the skeleton oil seal is generally to isolate the lubricated parts from the output parts required in the transmission parts, so as not to allow the leakage of the lubricating oil. It is usually used for the rotating shaft as a rotating shaft lip seal.

widely used

At present, more than 60% of the world's fluororubber production is used in the automotive industry. With this excellent performance, the scope is continuously expanded in various fields. At present, a large amount of fluororubber is used to produce oil seals.

According to reports, 50% of fluororubber is currently used for sealing products, and the proportion of fluororubber in Japan is as high as 80%, and fluororubber has become an indispensable high-temperature and corrosion-resistant rubber material.

So far, fluorine rubber skeleton oil seals are still widely used, and in this rapidly developing field, the reliability of elastomer gaskets is very critical. The changes can be said to be very small.

Due to its outstanding high temperature and corrosion resistance, it has the reputation of the king of rubber. It is processed into rubber pipes, tapes, films, gaskets, skeleton oil seals, O-rings, V-rings, etc., which are widely used in drilling machinery, oil refining equipment. , natural gas desulfurization equipment, at the same time, fluororubber oil seals are used in pumps and pipe joints, often with organic chemicals, for sealing inorganic acids, etc.
