What is an Oil Seal?
In these instances, Viton can be the perfect sealing material for methanol/ethanol-blended gasoline.
Before removing the cover, note the positions of any pipes and wires round it or fixed to it, which have to be removed before it can be freed.
Sealing principle: Since there is an oil film controlled by the oil seal edge between the oil seal and the shaft, the oil film has fluid lubrication characteristics.
The quality of the rubber or rubber fabric used to make an outer case is the same as the quality of the rubber sealing lip. Fabric reinforced rubber is, as the name suggests, rubber reinforced with a fabric.
Natural rubber gaskets are essential components in a variety of industries, from automotive to plumbing, and play a crucial role in preventing leakage and ensuring airtight seals. Made from high-quality natural rubber, these gaskets are known for their durability, flexibility, and resistance to a wide range of temperatures and environmental conditions. In this article, we will explore the benefits of natural rubber gaskets and the key factors to consider when choosing the right gasket for your specific application.
These cassette seals are widely used in wheel-end applications, such as the axles of agricultural machinery or off-road trucks.


Oil seals are found in a wide range of applications, in virtually every industrial sector. It is essential to select the correct oil seal so that the application in which it is used can run efficiently, free of leaks or other issues.

Storage and Handling


JTEKT provides special seals for use in a wide variety of machines and applications.
Table 5 lists the major special seals, their shapes, and their features.
Polyacrylate oil seals are a perfect compromise between quality and cost. They perform well with high temperatures and chemicals, but not as well as Viton oil seals. Polyacrylate has a temperature range of -25 degrees Fahrenheit to 300 degrees Fahrenheit. Due to their outstanding resistance to hot oil and oxidation, they are commonly used in automobile transmissions and hoses; however, they are also used for shaft seals, gaskets, and o-rings.
Construction of an Oil Seal
The oil seal would seal one face against a rotating member and the other face to a stationary housing. It would prevent dirt from coming between the hub or shaft and the seal.
