Trends dynamic seals

Over the decades, new materials have broadened the application range of oil seals significantly. Today they are used in deep or very high temperatures and are aggressive lubricants and alternative fuels permanently resistant.
The Energy Saving Oil seal “minimizes the frictional forces at full sealing function.

For the function of automobiles, machinery and industrial equipment seals have a crucial importance. The requirements for these components has increased, especially in the last two decades: they must be small and compact as possible, a long life with minimal wear, with the least possible friction and high compatibility with a variety of media. The vehicle, machinery and equipment manufacturers to choose their suppliers is seal carefully. A demand for specialists with extensive experience in the sealing environment in the development of elastomeric materials as well as a broad, innovative product portfolio for the complex application challenges.

The history of the classic seal Radial shaft seal dates back to the thirties, when Prof. Walther Simmer at Freudenberg developed the eponymous oil ring. This new seal replaced the until then to seal the bearing of shafts and axles used constructions made of cork or felt. With the oil ring of leather and metal of the groundwork for an exemplary series of innovations has been laid. The leather was soon replaced by synthetic rubber.
Compatibility with media to be sealed
Both in the past years as well as current developments in the compatibility of the oil seals playing with the media to be sealed a crucial role. To prolong the life of the lubricants and thus also to increase the units, always new and improved additives as well as lubricants are developed and implemented. It is obvious that the dynamic seals which reach even with these lubricants for close interaction, a high compatibility with these media must have. Any intolerance would be immediately and express it in a leak malfunction of the unit.
