Difference Between a Mechanical Seal and an Oil Seal

Here we describe the difference between mechanical seal and oil seal. Seals are important devices in any mechanical engineering setup because they function to prevent or limit the leakage of fluids. Not just that, they have a crucial role in applications that have components that do not have movements significantly different from each other.

Seals play a crucial role in applications that have a significant movement from rotation or reciprocation. The seals offer the inlet and outlet of a rotating shaft. Normally, it is used to prevent high-pressure fluid leaking into a low-pressure fluid.

Their primary purpose is to reduce, limit, or prevent any potential flow, which might arise between two components of a machine.  In locations where machine designs have pressurized fluids that require contaminants within a defined area, like hydraulic cylinders.

Mechanical Seal and Oil Seal- a comparison

When we talk about seals, they are mainly of two types- oil seals and mechanical seals. In various mechanical engineering applications, they are used. But the question is how they are different from each other. What are their distinct features?

Oil seals or rubber oil seals or oil gaskets or dirt seals are the same things. They prevent leakage associated with the lubrication of oil in mechanical equipment or component. They close the space between moving and stationary components. Precision bearings are especially useful. It prevents corrosive moisture from seeping into the bearings.

The shape and size of the oil seal vary in shape and size. They are made in such a way that they fit into various types of pipes, valves, and other openings.

As far as mechanical seals are concerned, they are used to contain fluid within a mechanical vessel, e.g., a pump and mixer. Here, a rotating shaft passes through various stationary housings. In some cases, the housing rotates around the shaft.

As far as the difference between a mechanical seal and an oil seal is concerned, a mechanical seal has three sealing points. The stationary part of the seal is fitted to the housing with a static seal. An O ring is used to seal the rotary portion. It can seal the faces well.

The fluid film is another aspect that makes a difference between mechanical and oil seals. The majority of mechanical seals need a certain level of lubrication. The necessity of lubrication is made possible by the thin film of fluid present in the two faces of the seal. These are the differences between a mechanical seal and an oil seal.
