Cassette seals are designed to maximise grease or oil retention and protection against liquid or solid contaminants. These seals are provided with their own bushings in which dirt is kept out and oil/grease kept in by a multi-lip seal.

Oil seals are used in a great many machines.
Different types of rotary shaft seals are available in the market, including radial lip, axial lip, and mechanical face seals.
Dynamic seals called bearing isolators are used to shield bearings from external impurities. They are revolving (rotor) and stationary (stator) elements. O-rings or strong seals are used in some bearing isolators, while they are constructed like labyrinths in others.
It is critically important that you choose the appropriate seal for an application. The seals should be ordered from a manufacturer of high repute. To get the best seals, it is important to give accurate design specifications. We describe the difference between mechanical seal and oil seal here.
we offer oil seals made from the highest quality materials to ensure durable, reliable seals for a variety of applications. Our state-of-the-art machining services allow us to deliver custom seals to meet customer requirements for quantity, size, style, profile, and materials.

Most oil seals consist of some basic elements that configure their structure, such as the sealing element, the metal case, and the spring:
Sealing lip
On some engines you have to remove the clutch-housing cover to reach the rear nuts.
First, an elastomer, most often nitrile, is vulcanised to a metal ring. This creates a stiffening effect that includes a specialised metal tension spring directly behind the sealing lip, keeping the oil seal firmly in place against the moving part.
The most common and economical material within the sealing industry, Nitrile, is used in many oil applications, the automotive sector for aircraft fuel applications, military and marine applications, and more.
