- Oil Seal Dimensions A Comprehensive Guide
- In conclusion, spare parts and oil seals, though often overlooked, are indispensable elements in machinery maintenance. Their role in preserving the operational efficiency, minimizing downtime, and preventing costly repairs cannot be understated. Therefore, it is essential for businesses and individuals alike to invest in quality spare parts and oil seals, maintain a robust inventory, and conduct regular checks to ensure their machines run smoothly and efficiently. After all, prevention is always better than cure, and in the world of mechanics, a well-maintained machine is a productive one.
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.
Common lip materials available for use in our oil seals include:
Oil seals are used in a great many devices for steel production equipment.
Figure 7 shows the places where each seal type is used in a rolling mill.
2. Temperature: Just like pressure, it is very important to choose the right seal that can withstand extreme heat or cold temperatures, depending on the operating environment of your application.


The mating surfaces of the head or block must be perfectly clean, flat and smooth.
6. Check for Leaks
Start the engine and check for oil leaks.
Corteco is a well-known brand in the automotive industry, supplying top-quality oil seals, including the first Simmerring® in 1929. The range consists of more than 7000 gaskets and more than 6500 OE-quality shaft and valve stem seals.
The basic principle of sealing is straightforward – the flexible lip is held against the rotating part (usually the shaft) whilst the casing (or O.D.) is pressed into the housing or bore and holds the seal in place. The sealing lip needs some form of lubrication to avoid overheating and is usually energized by means of a garter spring.
Conventional oil seals are the traditional seals, which can be recognised by a spring on the inside. These oil seals are made of a metal housing that contains a rubber seal. This part is often made of elastomer and comes into contact with the surface of the rotating shaft.
