- Porcelain spark plugs are an essential component in the ignition system of most gasoline-powered vehicles. Made from a ceramic material, they play a critical role in creating the spark that ignites the air-fuel mixture in the engine's combustion chamber. This ignition process is what powers the vehicle and allows it to run smoothly.
- Oil seals are essential components in the lubrication and maintenance of mechanical systems. They are used to prevent leakage of oil or other lubricants in machinery, automobiles, and industrial equipment. Understanding the various dimensions of oil seals is crucial for their proper selection, installation, and maintenance.



Main lip The main lip is the most critical component of the seal.
Make sure the fuel-pipe connections are clean. Unplug them and reconnect to the pump.
Have two plugs, such as old pencils, ready to fit the pipes. Unscrew the pipe connections and plug them at once.
An ignition spark plug is a crucial component in the internal combustion engine of a vehicle. It plays a key role in starting the engine and ensuring it runs smoothly. Without a functioning spark plug, the engine would not be able to ignite the air-fuel mixture, resulting in the vehicle being unable to start.
Step-by-step plan for correct installation
When installing a product, people often ignore the instructions because there is an idea that we can do it ourselves. However, oil seals are fragile devices that require attention and specific instructions to be followed before and after use.
Mechanical seals, like oil seals, can be easily damaged during installation. Taking the time to read the installation manual will provide you with step-by-step information on the correct installation or replacement of oil seals.

Refit the rocker or cam cover, aligning its fixing holes with those on the head. Check that the gasket edge aligns with the cover flange all round, and is not distorted. If necessary, adjust it gently with tweezers or long-nosed pliers. Tighten bolts evenly to just compress the gasket.
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.
