- Proper Cleaning: Dirt, grime, and debris can damage the sealing surface, leading to leaks. Regular cleaning of the seal and surrounding areas can help prevent this.

Oil Seals 101 – Part 1
- A well-designed and properly installed front valve cover gasket can significantly improve engine efficiency by reducing oil leakage. This is because a faulty gasket can cause oil to seep out, leading to reduced oil pressure and poor lubrication of the engine's moving parts. Over time, this can cause significant damage to the engine, resulting in costly repairs or even premature engine failure.




Despite being a great substitute for more expensive high temperature resistant materials, polyacrylate has a problem of poor water compatibility and cold flexibility.
Today, traditional oil seals have to compete with a new variant oil seal, which is used in most modern engines.

front hub oil seal. Most mechanics recommend replacing the front hub oil seal every 60,000 to 80,000 miles, but this can vary depending on your driving habits and the conditions in which you drive.
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.

The black color of these spark plugs is a result of carbon buildup, which is a common issue that can occur over time due to normal engine wear and tear. This carbon buildup can negatively impact the performance of the spark plug, leading to misfires, rough idling, and poor fuel efficiency. It is important to regularly inspect and replace black spark plugs to ensure optimal engine performance.
Why are sealed bearings favored over the unsealed alternative? Why ought sealed ball bearings be preferred to unsealed ones? What advantages can sealed ball bearings offer?
To diagnose potential problems with the ignition spark plug, there are a few signs to look out for. These include difficulty starting the engine, decreased fuel efficiency, and engine misfires. If you notice any of these symptoms, it is important to have your spark plug inspected and replaced if necessary.
