Oil seals are also known as grease seals. It works like glue between two surfaces to remove the space of a mechanical tool. It can resist non-lubricity. It can prevent foreign object from entrancing a machine. It gives a proper function to any machine to boost automobile actions.

Oil seals are safe and secure especially for roller, tight fitting ball bearings, precision constructed tools and sleeves. It helps to maintain the lubricity in a precision bearing or in other words, it doesn’t allow the grease move to any particular area. It works as a protector against massive moisture in machinery tools.

For precision bearings, rubber seals help prevent lubricants from running away from the bearings or spilling off in a specific area. For machine components, this tool helps prevent corrosive moisture, abrasives and stops any harmful contaminant from entering the machine. Seals also help prevent inner mixture of two kinds of medium such as water and lubricating oil.

Oil piston seals avoid dirt in a machine. It is flexible and actually strokes a tube and prevents the leakage. The edge of the seal should be adjusted towards the material, which is controlled. Some of the seals also have a spring to adjust the point within contact of the tube.

The direction of sealing is very important in consideration of the oil seal and seal gasket. The direction of sealing can be done internally or by rod seal and externally or by piston seal. Rod seals are radiating seals and directly connected. This is contacted with a shaft and forcefully adjusted into a housing bore. Piston is also of the same type. But it is adjusted into a tube with a sealing point, which is added to a housing bore. An example of external seal is V seal. A symmetric seal is parallel and works simply as a rod or a piston seal. The axial seal works axially as alongside of a machine part or housing.
