  • The '6%' in the seal's description usually refers to the lip's thickness or the percentage of the seal's cross-section that comes into contact with the shaft. This percentage contributes to the seal's effectiveness in maintaining a tight barrier against oil escape. A higher percentage typically indicates better sealing capabilities, but it also increases friction, which may affect the longevity of the seal and the rotating component it contacts.
  • The block is unlikely to distort except after severe overheating, but check anyway using a steel ruler or similar high-quality straight-edge.

  • When the oil seal fails, it can lead to a variety of issues. Leaking oil can cause the wheel bearing to overheat, reducing its lifespan and potentially causing failure. Contaminants entering the bearing can lead to increased friction and wear, necessitating costly repairs. Moreover, oil leakage on the brakes can compromise their effectiveness, posing a significant safety hazard.
  • If the shaft or housing gets damaged, it must be repaired. If you replace only the oil seal, but the shaft or bore remain damaged, then there is a chance of premature failure or leakage. You can easily repair the shaft, for example using an SKF Speedi-Sleeve.

  • In conclusion, changing a valve cover gasket is a relatively straightforward task that can significantly improve your vehicle's health. With the right tools, a bit of patience, and attention to detail, you can save money on mechanic fees while maintaining your car's engine in top condition. Always prioritize safety and follow best practices to ensure a smooth and efficient repair job.
  • Fitting an oil seal

  • Oil seals work by squeezing and retaining lubricant in a thin layer between the lip and the shaft. Perfect sealing is ensured by the hydrodynamic action of the rotating shaft, which in turn produces a slight pump action.

  • Furthermore, the 30-50-10 oil seal is designed to withstand prolonged use and harsh operating conditions. This makes it suitable for a wide range of applications, including automotive, industrial, and agricultural machinery.


  • One of the key factors that determine the effectiveness of an oil seal is its design. Engineers must consider factors such as the shape, size, and material composition of the seal, as well as the specific requirements of the machine it will be used in. For example, a seal used in a high-pressure environment may need to be reinforced to withstand the increased forces.
  • The white color of these gaskets is often preferred in certain industries as it provides a clean and professional appearance. In addition, white rubber is typically made from materials that have good resistance to heat, chemicals, and weathering, making it suitable for use in demanding environments.
  • 2. Installation Techniques Use the appropriate installation techniques for the specific application. For example, in an automotive engine, use a torque wrench to ensure proper torque is applied.
  • In the realm of machinery and equipment, the oil seal serves as a vital component, ensuring smooth operation and extending the life of the system. This tiny yet indispensable device is designed to prevent the leakage of fluids, such as oil and grease, while allowing for the rotation of moving parts.
  • Concentricity

  • Overall, the oil seal 12 22 5 is a crucial component in industrial machinery and automotive systems. Its ability to prevent oil leakage, maintain lubrication, and protect the equipment from external factors makes it indispensable for ensuring the smooth operation and longevity of the machinery.
  • Oil seals are typically made from high-quality materials such as synthetic rubber, polytetrafluoroethylene (PTFE), or metals like stainless steel. These materials are chosen for their ability to withstand the harsh environments where oil seals are commonly used. For instance, a rubber oil seal might comprise 20% synthetic rubber, imbuing it with the necessary flexibility and resilience to form a tight barrier against oil. Meanwhile, a metal oil seal could consist of 30% stainless steel to provide strength and durability.
  • High- and low-temperature-resistant type
  • Broad chemical resistance, except against liquid alkaline metals and fluorine gas under pressure. Good sliding qualities, low wear and tear. Temperature range from -200 °C to +260°C. PTFE has hardness of approximately 95 °Shore and installing these O-rings in split grooves is recommended or alternatively the use slit or sheathed types due to the low elasticity.

  • 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.)
