- Performance criteria are established in the oil seal standard to ensure that the seal meets certain performance benchmarks. These criteria may include factors such as maximum pressure, temperature range, and expected lifespan. Manufacturers must test their seals to ensure that they meet these performance criteria before they are sold to customers.
- A reputable high pressure oil seals supplier will have a good track record of providing high-quality seals that meet industry standards. They will also have a reliable manufacturing process that ensures consistency and precision in their products. It is important to choose a supplier who can provide custom seals tailored to your specific requirements.
Recognizing and avoiding common installation mistakes is key to the longevity and effectiveness of oil seals. Here are some frequent errors to watch for:
- When choosing the right oil seal for a specific application, it is important to consider factors such as operating temperature, pressure, speed, and the type of fluid being sealed. Proper installation and maintenance of oil seals are also critical to ensure optimal performance and prevent system failure.
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.

What are Oil Seals and how do they work?

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.

(5) The surface finish of the shaft directly affects the service life of the oil seal, that is, the higher the shaft finish, the longer the service life of the oil seal.

Case study 3: Product changes in oil seals
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.
