The major cause of extrusion and nibbling is stress caused by high pressure. This is commonly noticed when the oil seal has a chipped or nibbled look. In fact, in some cases, the surface of the seal tends to peel on its own, which makes it have a shaved look. What the stress does is that it increases the clearance gap between the mating edges, which causes the seal to get entrapped, and then leads to severe physical damage.

(5) The surface finish of the shaft directly affects the service life of the oil seal, that is, the higher the shaft finish, the longer the service life of the oil seal.
Aluminum alloys and resin (materials with a large difference between the linear expansion coefficients) demand sufficient consideration (as there is a risk of failure due to the increased clearance with the oil seal at high temperatures).


Nitrile Butadiene Rubber (NBR, nitrile)
In conclusion, U-shaped silicone gaskets, white rubber gasket sheets, and waterproof rubber gaskets offer versatile and effective sealing solutions for a wide range of industrial and commercial applications. Understanding the advantages and applications of these gaskets is crucial for selecting the appropriate sealing components to ensure protection, reliability, and longevity in various systems and equipment.
