- In addition to its sealing capabilities, the 45 62 8 oil seal also provides excellent resistance to wear and tear, as well as temperature and chemical exposure. This makes it a reliable choice for demanding applications where reliability is paramount
oil seal 45 62 8.As an example, this oil seal has a part number that corresponds to a Shaft Size of 3”, a Bore Size of 4”, a Width Size of 0.625”, a Style of TB2, and is made of Viton material. Conversely, the same size oil seal in Metric has a Shaft Size of 76.20 mm, a Bore Size of 101.60 mm, and a Width Size of 15.88 mm.
- When replacing, the PTFE sealing lip of the new oil seal should not be in the same position as the old oil seal. The diameter of the sealing lip should be smaller than the shaft diameter.
- Introduction
- et engine spark plugs are designed to withstand the high temperatures and pressures inside a combustion chamber, as well as the harsh conditions experienced during flight. They are typically made from materials such as iridium, platinum, or nickel alloys, which have high melting points and excellent thermal conductivity. This allows the spark plug to ignite the fuel-air mixture consistently and efficiently, even under extreme operating conditions.
- Rubber is also a popular choice due to its flexibility.
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.
It is generally used in the union of two lubricated parts, so that it hermetically seals both sides. Therefore, it guarantees the proper engine operation and helps to maintain the vehicle’s distribution system in better condition.

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.
The History and Applications of Oil Seals
The maximum allowable shaft speed is a function of the shaft finish, runout, housing bore and shaft concentricity, type of fluid being sealed and the type of oil seal material.
Oil seals, which are also known as rotary shaft seals, fluid seals or grease seals, play an important role in closing down the gaps between moving and stationary elements of mechanical equipment.
