CASSETTE Oil Seal
Cassette seals are compact units that combine several sealing and protective elements: the main lip, the dust lip and a metal housing. Thanks to this design, they operate effectively in environments containing dust, mud, water or other contaminants. They are commonly used in heavy industry, agriculture, construction and on off-road vehicles. At Hydraulic Seals Store, you’ll find cassette seals in a range of sizes, available from stock, with fast delivery anywhere in Romania.
What are cassette seals and for which applications are they recommended?
Cassette seals are an advanced sealing solution for rotating shafts in contaminated environments. Their compact, integrated design reduces the risk of incorrect fitting and ensures more consistent performance compared to conventional seals. See also DC and AS seals for other sealing solutions with advanced protection.
Features of cassette seals
Special design for complex protection and sealing
A cassette seal comprises two concentric metal rings, between which the sealing elements are located. The inner ring is fitted onto the shaft, whilst the outer ring is secured in the housing. The main lip retains the oil, whilst the dust lip prevents contaminants from entering.
Good resistance in harsh operating conditions
Cassette oil seals are highly resistant to abrasive dust, mud, water and other aggressive contaminants. Thanks to their metal construction, they are stiffer than rubber oil seals and wear less easily under harsh conditions.
Where cassette oil seals are used
- drive shafts for tractors, combine harvesters and agricultural machinery;
- construction machinery: excavators, bulldozers, tipper lorries;
- axles and axles for off-road vehicles and heavy machinery;
- industrial gearboxes and transmissions exposed to contaminated environments;
- forestry and lifting equipment used in off-road conditions.

Frequently Asked Questions
What makes cassette seals different from standard seals?
Cassette oil seals feature an integrated design with two metal rings and multiple sealing elements, making them more effective than standard oil seals. They are easier to fit and there is less risk of installation errors.
Under what working conditions is a cassette oil seal most suitable?
Cassette oil seals are suitable for applications where there is a lot of dust, mud, water or other contaminants, such as agricultural machinery, construction machinery or off-road vehicles.
How does the cassette design help protect against dust and dirt?
The cassette-type oil seal has an additional dust lip and a rigid metal housing, which prevents contaminants from reaching the main lip. As a result, the oil seal lasts longer.
How do you choose the correct size for cassette oil seals?
Select the cassette oil seal based on the diameter of the shaft and the housing, as specified in the equipment’s technical specifications. You can consult the technical documentation or contact us for assistance.
