Classical oil seals consist of a metal housing that carries the dynamic sealing lip and provides the static sealing function. These are usually manufactured of elastomer material, such as ACM, Silicone or FPM. Further, since they are in contact with the surface of the rotating shaft, the lip is pressed onto the shaft surface by means of a spring ring.


Carefully lower the sump from the crankcase.






The sealing effect is achieved by manufacturing a smaller inside diameter than the required shaft size, which preloads the sealing lip. A garter spring is often used to ensure a constant force on the shaft.
These cassette seals are widely used in wheel-end applications, such as the axles of agricultural machinery or off-road trucks.
All are fitted with a spring to preload the sealing lip. All these types are for non-pressurised or low-pressure applications up to 0.5 bar for diameters of a limited size. For diameter of 500 mm or more, the maximum pressure is 0.1 bar. For higher pressures, special types or PTFE lip seals can be used.
As shown in Figure 1, sealing devices come in two types: contact and non-contact.
Oil seals are among the major contact type sealing devices.
Materials used
Oil seals normally consist of three basic components: the sealing element, the metal case, and garter spring.


It is important for the spark plug to produce a strong and consistent spark in order for the combustion process to be efficient. Over time, the spark plug can become worn or dirty, which can affect its performance. This is why it is recommended to regularly inspect and replace spark plugs as needed to ensure optimal engine performance.
