Auto Oil seal structure

The oil seal is generally composed of three basic components: sealing element, metal shell and clamping spring.Types of oil seals include single and double lips, rubber or polymer, metal housing, spring loaded, and internal, external and axial guides.

Types of Automotive Seals
There are a lot of seals that the automotive industry use but there are two types of seals that are commonly used. These seals have also found their way into other industries. Below are the different types of automotive seals that also have mechanical applications.

O-RINGS SEALS
O-rings are made from elastomeric materials. They function by sealing two adjacent surfaces thus keeping the liquids contained from within a particular system. They are designed to take on extreme pressure and temperature as well as corrosive gases and liquids. They are designed to have a contact with the sealing face. It is very flexible. Thus, allowing it to accommodate any imperfections on the mounting surfaces.

It is considered as one of the most common type of seals used in machines as they are cheap and very easy to manufacture. They are also very reliable and have simple requirements, making the mounting process less complicated. Also called toric joint or packing, O-rings also have mechanical applications especially where relative motion between parts are involves. They are used to contain pressure and fluid. O-rings are used in vacuum applications to keep the pressure in check. They are also used to prevent leaks in pumps.

LATHE-CUT SEALS
Lathe cut seals are used similarly with O-rings. They are made from a rubber tubing that has been inserted with a mandrel to cut the desired dimension. They provide more cost-performance benefits especially when static seal is needed. Unlike O-rings, lathe-cut seals provide wider surface for sealing thus making it more resistant against compression. They are also less expensive making them great for high volume gaskets.

LIP SEALS
This type of seal is used in rotating shafts. The lip provides a seal from a low-pressure chamber. It is installed in the pressure source and it balloons out to provide tight sealing. They are used in motors as well as reversible motors. They are also used in devices that need to maintain vacuum conditions to preclude dirt and contamination for entering.

PACKING
Packing is a type of woven fiber that are packed between parts that needed to be sealed. This type of packing can be dynamic or static. It functions as a rotating shaft seal and gasket in different types of application. It is placed in a bore and compressed by a flange in automotive parts. It can also be used to seal a pump. In fact, industries like the paper manufacturing and milling use packing seals to prevent leaks.

Seals are created to prevent leaks. There are different types of leaks that are used in different industries but it is important to take note that even if they are designed to cater to the automotive industry, they have profound mechanical applications.
