Oil seal is used to seal rotating shafts. Oil seals are also known as
rubber oil seals,
oil gaskets,
dirt seals.
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®.
The most widely used oil seals are in the
automotive industry,
machinery industry,
agricultural industry.
Gumet has been producing oil seals for over 20 years, gaining extensive experience in this field. We mainly produce non-standard oil-seals according to technical documentation and specific requirements of end customers, mainly from the automotive industry and agricultural machinery
