The shaft surface to be in contact with the lip should be finished to
0.1 to 0.32 μmRa and 0.8 to 2.5 μmRz
and the lead angle to no greater than 0.05°. (There is a risk that the lead marks will impede the sealing performance of the oil seal: see Figure 5.)Oil seals, which are also referred to as radial shaft seals, rotary shaft seals, grease seals, or fluid seals, are used to close the gaps between fixed and moving parts of mechanical equipment. They are put between moving and stationary mechanical parts to make sure that moisture, contaminants, corrosive materials, and abrasives don’t cause any damage to these parts.
- Furthermore, the B20 series valve cover gasket helps to maintain compression within the cylinder head
- Another important role of the power steering oil seal is to prevent air from entering the system. Air bubbles in the power steering fluid can cause a phenomenon known as air lock, which can make it difficult or impossible to turn the steering wheel. This can be particularly dangerous when driving at high speeds or in emergency situations. The power steering oil seal helps to maintain a steady flow of fluid, ensuring that the system operates smoothly and efficiently.

oil seal 20 34 7. Its dimensions indicate that it has a 20mm inner diameter, a 34mm outer diameter, and a 7mm width. This size is suitable for a variety of applications and can be easily installed in most types of machinery.
No matter the PTFE machining techniques and other processes used in making mechanical parts, they tend to fail due to some reasons. The same thing applies to oil seals. When they are exposed to some factors, they fail. The factors are stated below alongside the solutions.


An overview of the different standard types of oil seals and their main characteristics is shown below.
