4. SHAFT SPEED: As different shafts move at different speeds you need to consider the runout, the housing bore, and oil type being sealed. Ensure you select a seal that will not suffer from abrasions or spiralling.
In the construction industry, gasket rubber seals are used to provide weatherproofing and soundproofing in buildings. Door and window frames often feature rubber gaskets to prevent drafts and moisture infiltration, while floor tiles may include rubber underlayment to reduce noise transmission between floors.
Where loads are light, the outer skin layer can be made of silicone. It can be made of Fluroelastomer (orViton) to protect under high temperatures (more than 120 degrees Celcius). The skin can also be made of Poly Acrylate or Polytetra-FluroEthylene.

The role of the micro spark plug in triggering combustion is akin to the catalyst that ignites innovation in business and science. Just as the spark plug provides the essential energy to power an engine, entrepreneurs and scientists need that initial motivation—that spark of curiosity or necessity—to drive their projects forward. However, unlike the predictable combustion initiated by the plug, the outcomes of these undertakings can be unpredictable, leading to groundbreaking discoveries or entrepreneurial successes.Several variables, including maximum temperatures, required lubricants, available space, and more, may influence your choice of bearing seal. Each factor can affect the type of bearing best for your application, the amount of material required, and other factors. Although the choice of seals is crucial to the effectiveness of your bearings, you don’t have to make that choice alone. Our experts at NBC bearings can collaborate with you to identify the bearings and bearing seals that provide the best, most affordable solution for your application, environment, and finished product.
Operating conditions such as the engine’s temperature, position, size, pressure and shaft speed largely determine which individual oil seal composition is most suitable for every individual application.
