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.
- In conclusion, the percentages 20%, 30%, and 7% are more than just numbers; they embody the science behind oil seals. They symbolize the delicate equilibrium between flexibility, strength, and durability that is essential for effective sealing solutions. As technology continues to evolve, so will the composition and performance of oil seals, ensuring their pivotal role in safeguarding the smooth operation of machinery across industries.


Auto Head Gasket: Importance in Engine Functionality
Modern engine concepts, like higher engine speeds and oil temperatures, longer intervals between oil changes and lubricants with modern additives, require new solutions for dynamic seals. They have to withstand the high loads lastingly. PTFE technology is the answer, since it perfectly meets these demands.
(4) The degree of eccentricity on the installation If the eccentricity of the oil seal and the shaft is too large, the sealing performance will be deteriorated, especially when the shaft speed is high. If the eccentricity is too large, a W-shaped oil seal can be used.
