Oil seal is used to seal rotating shafts.
Oil seals are also known as
An oil seal is a component consisting of a metal insert (metal case) covered by rubber and with a sealing lip. Additionally, oil seals intended for use in highly contaminated conditions may have one more anti-dust lip. Garter spring is very often found in oil seals the job of which is to press the sealing lips to the surface of a rotating shaft.
A special type of oil seal is the cassette seal, which is a multi-lip version used in highly polluted environments (e.g. agricultural machinery).
Oil seals are used with rotating elements operating in oil, grease or other liquids. There are also oil-seals in a metal housing.
For the production of oil seals mainly NBR oil-resistant rubber mixtures are used (work at -40 ° C to 120 ° C), and in oil-seals that operate at elevated temperatures (-20 ° C to 220 ° C), a fluorine FKM compound is used, commonly known as Viton®.
