Fluororubber(FKM) skeleton oil seals are high-performance sealing materials extensively used in aerospace, chemical processing, petroleum, and automotive industries. The primary material, fluororubber(FKM), is a high polymer synthetic elastomer with fluorine atoms attached to the carbon backbone, giving it unique and exceptional properties.
Advantages of
Fluororubber(FKM) Skeleton Oil Seals
Renowned for their outstanding heat resistance and chemical stability, fluororubber(FKM) oil seals are highly durable in a variety of applications. fluororubber(FKM) itself is a non-toxic, odorless, non-flammable, semi-transparent elastomer that remains stable at high temperatures without degrading. Its excellent resistance to oils and chemical agents allows it to endure prolonged exposure to these substances without corrosion, making it ideal for harsh operational environments.
Structure of Skeleton Oil Seals
A typical fluororubber(FKM) skeleton oil seal consists of three main parts: the seal body, reinforced skeleton, and self-tightening helical spring. The seal body is further divided into distinct sections such as the base, waist, edge, and sealing lips. Once installed, the seal maintains its sealing performance through the radial tightening force of the sealing edge combined with the compensatory force from the self-tightening spring.
Application and Widespread Use
Globally, over 60% of fluororubber(FKM) is used in manufacturing oil seals for the automotive industry, attributing to its remarkable heat and chemical resistance. Where 80% of fluororubber(FKM) applications are in sealing products, highlighting its critical role. The main function of skeleton oil seals is to separate lubricated components from external power output parts, preventing lubricant leakage. This is particularly essential for rotating shaft lip seals.
High Temperature and Chemical Suitability
Fluororubber(FKM) skeleton oil seals are prized for their stability in high-temperature and humid environments. The physical properties of fluororubber(FKM) remain relatively unchanged under such conditions, earning it the title “king of rubber.” This material is not only used for oil seals but also creates hoses, rubber sheets, films, gaskets, O-rings, and V-rings, applied in drilling machinery, refining equipment, natural gas desulfurization, and pump and pipe fittings. Its performance in sealing organic chemicals and inorganic acids is exceptionally reliable.
FKM skeleton oil seals have become indispensable components in modern industry due to their superior physical and chemical properties, ensuring reliable operation under severe conditions.
