  • is saturated with the hydrogenation of the hydrocarbon chain of the nitrile rubber. This special hydrogenation 
  • Silicone gasket sheets are equally at home in the construction sector, where they serve as weatherstripping around windows and doors, preventing drafts and reducing energy loss
  • Another significant advantage is their compatibility with a wide range of fluids, from lubricating oils to harsh chemicals
  • 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.
  • Another important consideration is the compatibility of the main bearing oil seal with the engine's oil. The seal must be designed to withstand the chemical properties of the oil, such as its viscosity and additives, without deteriorating. Using the wrong type of oil can cause the seal to fail prematurely. Therefore, it is essential to use the recommended oil type for your engine to ensure the longevity and reliability of the main bearing oil seal.

  • The main causes of external lubricant leakage from pumping systems, hydraulic machines, gearcases and sumps are the wrong selection, improper application, poor installation and inadequate maintenance practices that are applied to sealing systems.

  • 1. **Preventing Leakage** Oil seals are designed to prevent the leakage of oil or other lubricants. Incorrectly sized seals can lead to costly leaks and system failures.
  • Figure 14.3. Oil aging of fluoroelastomers.5 Chart shows percent retained elongation. Conditions: Aged at 150°C in Service Fluid 105 (oil changed every 168 h).

  • Choose a seal that has the appropriate dimension needed for your application. The seal should properly fit the space between the stationary and rotating parts.
