Cassette Oil Seal

1. Description

Cassette seals are reliable rotary sealing solutions that are effective against multiple heavy-duty pollutants, such as dust, jets of water, mud and stones, UV rays, aggressive fluids, etc. Internal dynamic and static sealing systems provide ultimate protection from any external soiling and contamination that will otherwise compromise application performances and adversely affect vehicle reliability. Each cassette seal consists of an oil seal and a sleeve, which have been unitized. Labyrinth seal technology protects them from external soiling.

2. Materials

NBR (Nitrile Butadiene Rubber)

Nitrile rubber (NBR) is the general term for acrylonitrile-butadiene copolymer. The ACN content can vary between 18% and 50%. While the acrylonitrile content is important, the resistance to oil and fuel is more so. Conversely, the elasticity and compression set are not as good. The NBR has good mechanical properties and good wear resistance. However, its resistance to atmospheric agents and the ozone is relatively low.

FKM (fluorinated rubber)

Depending on their structure and fluorine content, the chemical resistance and resistance to the cold in fluororubbers can vary. This FKM-based rubber is very often used for high-temperature hydraulics and pneumatics, for industrial valves, injection/fuel systems, motor seals and high-vacuum systems
