Failure Modes of Oil Seals
- The Art and Science of Oil Seal Manufacturing
These new oil seals can also be equipped with a shaft rotation sensor.
The reasons for the birth of this new generation of seals is that integrated oil seals reduce the manufacturing time of series production engines. Therefore, significant time savings are achievable when replacing the radial crankshaft 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.
Choosing and using the proper sealing devices within oil and gas applications can be vital when preventing dirt, dust, water, and other debris from potentially getting inside and contaminating products.
4. SHAFT SPEED: As different shafts move at different speeds you need to consider the runout, the housing bore, and oil type being sealed. Ensure you select a seal that will not suffer from abrasions or spiralling.
- 2. Chemical resistance High temperature rubber gaskets are resistant to a wide range of chemicals, including acids, bases, and solvents. This property makes them suitable for use in chemical processing industries.

• Hydrogenated nitrile rubber
As shown in Figure 1, sealing devices come in two types: contact and non-contact.
Oil seals are among the major contact type sealing devices.

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.

Types Of Motor Oil
Conventional Motor Oil


The functionality of oil seals in between machines cannot be emphasized. Apart from their primary function of preventing the entry and escape of elements that can damage the machines, they also help to elongate the machines’ lifespan.
Foam inhibitors: This additive does exactly what it sounds like. Foam inhibitors keep motor oil from forming foam and bubbles. If foam and bubbles were to form, the oil would be unable to coat the important parts of the engine and keep it cool.
