Leather is probably the oldest of the lip materials still in common use, but the move towards mass production methods has seen a massive increase in the development of synthetic rubbers which lend themselves to accurate and repeatable injection and compression moulding. Nitrile (NBR) is still by far the most common elastomer for “normal” use, whilst Viton® (FKM/FPM) is rapidly replacing Polyacrylate (ACM) and Silicone (VMQ) for high-temperature applications. Viton® also has high resistance to abrasion and chemical attack making it a preferred elastomer. Recent developments in the use of PTFE for Rotary shaft seals has caused widespread interest particularly for high-speed shaft rotation or poor lubrication applications.

In terms of size, oil seals are available in a wide range of dimensions to suit different shaft diameters and housing sizes. It is crucial to select the correct size seal to ensure a proper fit, as using an improperly sized seal can lead to leaks and premature wear.

- The spark plug is a critical component of any dirt bike's engine. It plays a key role in igniting the fuel-air mixture in the combustion chamber, which in turn powers the engine and drives the bike forward. Understanding the importance of the spark plug and how to maintain it properly is essential for every dirt bike rider. In this article, we will discuss everything you need to know about dirt bike spark plugs.

The Ultimate Guide to Oil Seals
Materials for Oil Seals
One of the main causes of black spark plugs is a rich air-fuel mixture. This means that there is an excess of fuel in the combustion chamber, which can lead to incomplete combustion and the production of carbon deposits. A rich air-fuel mixture can be caused by a variety of factors, including a faulty oxygen sensor, a clogged air filter, or a malfunctioning fuel injector. It is important to address these issues promptly to prevent further damage to the spark plugs and the engine.

It is wedge-shaped to be pressed against the shaft surface and makes contact with the shaft to ensure sufficient sealing performance and suitability for operation at high peripheral speed.


Assembling the oil seal
Unthinkable in the list of seals are oil seals, which provide a seal against splashing oil. The most important oil seals are used for rotating shafts and valve stem seals. Oil seals are intentionally never completely sealed to lubricate the seals and prevent wear.
Seals are classified by O.D. wall material, lip type, and whether they have a spring or not.
Major oil seals are specified in ISO 6194-1 and JIS B 2402-1.
Table 2 shows the common types of oil seals, while Table 3 shows the features of each type of oil seal.
Table 4 lists the JTEKT oil seal type codes and corresponding ISO and JIS standards.
