description Freudenberg Simmerring Overview
The Freudenberg Simmerring is a brand name for a radial shaft seal, which has become a proprietary eponym for this type of component in many regions. Developed by the German technology company Freudenberg, it is designed to seal rotating shafts in automotive and industrial machinery. The seal typically consists of an elastomer lip with a metal garter spring that maintains contact with the shaft, preventing lubricant from escaping and contaminants from entering. This device is essential for the longevity of mechanical systems.
help Freudenberg Simmerring FAQ
What exactly is a Freudenberg Simmerring?
A Simmerring is a proprietary name for a radial shaft seal developed by the German technology company Freudenberg. It is designed to seal rotating shafts, preventing the leakage of oil and fluids in automotive and industrial machinery.
Why are radial shaft seals often called 'Simmerrings'?
The term became a genericized trademark because the inventor, Walther Simmer, worked with Freudenberg to patent the component in 1929. In Germany and many parts of Europe, 'Simmerring' is the universally used word for a shaft seal.
Where are Freudenberg Simmerring seals commonly used?
They are most commonly found in automotive applications, sealing the crankshaft and camshaft in internal combustion engines. They are also heavily utilized in washing machines, hydraulic pumps, and industrial wind turbines.
What happens when a Simmerring seal fails in an engine?
When a Simmerring wears out or dries out, it loses its tight seal, leading to visible fluid or oil leaks. If left unfixed in an engine or transmission, this leakage can lead to catastrophic mechanical failure due to a lack of lubrication.
