What are bearing isolators?
Operating temperatures for engine oil seals (see Fig. 14.11 and cross-section of lip seal with garter spring in Fig. 14.22) vary widely, depending on engine design and location within the engine. Typically, the rear crankshaft seal is subjected to much higher temperatures than the front seal. Oil sump temperatures vary considerably, depending on provisions for oil cooling. This allows use of hydrogenated nitrile (HNBR), silicone, or acrylic elastomers for some seals in relatively low-temperature environments (120–140°C or 250–284°F). Standard fluoroelastomers (FKM), bisphenol-cured VDF/HFP/TFE terpolymers with 68–69% fluorine content, perform well in oil service up to about 160°C (320°F). More resistant fluoroelastomers are necessary for reliable long-term performance in more severe environments.
HIGH-QUALITY INDUSTRIAL OIL SEALS
- Installation and maintenance of high pressure oil seals are equally important. Incorrect installation can lead to premature failure, while regular maintenance checks can help identify and address potential issues before they cause significant damage. It is essential to follow manufacturer guidelines and use appropriate tools to ensure the seal's integrity is not compromised during installation.
