hub grease seal

oil seal for rotating shaft.
Moreover, oil seal companies play a vital role in innovation and research to develop new materials and technologies that improve the performance and longevity of their seals. They invest in state-of-the-art manufacturing processes and quality control measures to ensure the reliability and efficiency of their products. Additionally, many companies offer technical support and consulting services to help their customers select the right seals for their applications and optimize their performance.

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.
