Rotary shaft seals work by squeezing and maintaining lubricant in a slim layer between the lip and the shaft. Sealing is aided by the hydrodynamic action caused by the rotating shaft, which creates a slight pump action. Rotary shaft seals provide protection through two crucial functions.

The chemically resistant P.T.F.E. component is spring loaded, to force the flexible angular lip of the wedge, into tight contact with the shaft. The same spring force impacts a sufficient load to the rotary face to create a suitable seal interface, with a varied choice of standard stationary seats. Examples of PTFE Wedge Mechanical Seals

The seals are made to keep moisture and dust out of the machinery's inner constructions while having little to no impact on how well they work. Almost every lip seal is constructed to have a flexible inner part that creates a dynamic seal on the moving shaft, as well as a hard outer casing that statically matches the machine-end cover.

The selection of seal type depends on the shaft speed, working pressure and desired sealing effectiveness. Seals for rotary motion include ‘O’ rings, lip seals, face seals, sealing rings,

The lip seal excludes or includes (seals) a medium in one defined volume away from another, where leakage would be a product failure.

Lip seals are common in industrial applications, such as hydraulic pumps and axle seals. Instead of compressing two faces against each other, a spring compresses a rubber ring against the shaft. Tides Marine produces the SureSeal (an earlier version was called the StrongSeal) and Nautical Specialties offers the LasDrop DrySeal.

So what is a lip seal? Lip seals serve to protect lubricated moving parts and they do this by keeping the lubricant inside the bearing, and keeping contamination from dirt or other liquids out. The term lip seal is generally used to refer to what is correctly known as rotary shaft seals or oil seals or radial shaft seals.

The sealing lip of the flexible member is prepared by cutting away the flash that forms at the sealing edge during molding. A fine sealing edge provides adequate pressure on the shaft to prevent leakage. The "O" rings are light and flexible and under compression they deform to follow the component parts to be sealed. "O" rings have a long life.
