Oil Seals: page 147
Oil seals are sealing elements used to seal rotating shafts against oil or technical fluid leaks. They are fitted into special recesses in the housings, creating a dynamic seal through contact between the rubber lip and the shaft surface. Without functional oil seals, gearboxes, pumps and motors leak oil, the environment becomes contaminated and equipment efficiency decreases. In the Hydraulic Seals Store catalogue, you’ll find a complete range of standard and special oil seals, available from stock with fast delivery in Romania.
What are oil seals and what role do they play in technical systems?
A lip seal is a radial sealing element for rotating shafts, consisting of a metal housing, an elastic rubber element (NBR, FKM or other elastomers) and, in some variants, a spring to press the sealing lip into place. See also the categories for hydraulic seals and bushings for complete sealing and guidance solutions.
Types of oil seals available
Standard oil seals
Standard oil seals (types A, AS, V) are used in transmissions, gearboxes, pumps and motors to seal rotating shafts under normal operating conditions.
Pressure seals, V, A, AS, SA-TA, SB-TB, DC
In addition to the standard types, the catalogue includes pressure seals (for high-pressure systems), V-type seals (with a special protective profile), AS-type seals (with an additional dust lip), SA-TA, SB-TB and DC seals (for specific industrial and mobile applications).
CASSETTE seals
Cassette seals are compact units with integrated sealing and protection, used in demanding applications in heavy industry, construction and agriculture, where protection against dust and dirt is essential.
Applications for oil seals
- automotive and machinery transmissions;
- hydraulic pumps and hydraulic motors;
- gearboxes and gear units;
- axles and axles for motor vehicles and agricultural machinery;
- Industrial equipment with rotating shafts.

Frequently Asked Questions
What are oil seals and where are they used?
Oil seals are radial sealing elements for rotating shafts. They are used in transmissions, pumps, motors, gearboxes and shafts to prevent oil or technical fluid leaks.
How do I choose the right oil seals?
Choose the oil seal based on the shaft diameter, the outer diameter of the housing, the width, the lip material (NBR, FKM) and the operating conditions (pressure, temperature, rotational speed).
What is the difference between the various types of oil seals?
The types differ in terms of the sealing lip profile, the presence of a dust lip, the body construction and the ability to withstand pressure. The choice of type depends on the application and environmental conditions.
Can I buy oil seals online with delivery?
Yes, all oil seals in the Hydraulic Seals Store catalogue can be ordered online, with fast delivery to your address in Romania.
