How are they used?
Other important factors are ensuring the hardness and roughness of the shaft are correct. A shaft hardness of HRC 45 is recommended for a rubber sealing lip, with a roughness of Ra 0.4-0.8. A higher shaft hardness of HRC 60 and shaft roughness of Ra 0.1-0.4 is recommended for a PTFE lip.
4. Protecting the shaft from damage helps optimize your oil seals’ efficiency.
Scrape off all the traces of dirt and old gasket from the engine and sump flanges with a paint scraper.
Maintenance and Replacement of Oil Seals:
As the pressure increases, the radial load and the friction of the sealing lip increase in contact with the shaft. As with temperature, each oil seal has a recommended pressure for optimum performance. Excessive pressure causes the seals to wear more quickly and consequently have a shorter life.
Thoroughly clean the sleeve at the back of the pulley, and look for any roughness on it where it touches the seal. If necessary, smooth it with fine wet-and-dry abrasive paper.
(burr, corrosion, etc.), which will directly affect the service life of the oil seal.
Automotive Rubber Gaskets: Versatile Sealing Solutions
Regular inspection and maintenance of engine oil seals, power steering oil seals, and motor oil seals are essential to identify signs of wear, damage, or leakage. Proper lubrication and adherence to recommended service intervals can help extend the lifespan of these seals. When replacement is necessary, selecting the correct seal type and ensuring proper installation are critical to maintaining the integrity and performance of the vehicle's systems.
