  • Regular maintenance and replacement of the spark plugs are important for ensuring the continued performance of your engine. Over time, the electrodes on the spark plug can wear down, leading to weaker spark and reduced engine performance. By replacing the spark plugs at regular intervals, you can maintain optimal engine performance and prevent potential issues down the road.
  • OEM spark plugs, on the other hand, are designed and engineered specifically for each vehicle application by the manufacturers themselves. They take into account factors such as engine design, fuel type, and driving conditions to ensure optimal performance. As a result, OEM spark plugs offer several advantages over their generic counterparts.

  • Oil Seals: Function & Maintenance

  • Always start by making sure the oil seal is facing the right direction. The oil seal must be positioned with its spring to the side of the medium to be sealed. The oil seal must then be pressed into the bore. It must fit tightly (H8 in the groove is recommended). Use appropriate tools for this, such as an impact socket set, to ensure that the force is applied evenly during pressing. The oil seal must never be hammered into the bore with brute force, but eased in.

  • Leather is probably the oldest of the lip materials still in common use, but the move towards mass production methods has seen a massive increase in the development of synthetic rubbers which lend themselves to accurate and repeatable injection and compression moulding. Nitrile (NBR) is still by far the most common elastomer for “normal” use, whilst Viton® (FKM/FPM) is rapidly replacing Polyacrylate (ACM) and Silicone (VMQ) for high-temperature applications. Viton® also has high resistance to abrasion and chemical attack making it a preferred elastomer. Recent developments in the use of PTFE for Rotary shaft seals has caused widespread interest particularly for high-speed shaft rotation or poor lubrication applications.

  • In conclusion, while the testing of spark plug wires might seem like a minor task, it's a necessary evil for those who appreciate the science behind the smooth operation of an engine. By regularly checking and maintaining these crucial components, drivers can avoid unwelcome surprises and enjoy a more responsive, efficient drive. It's all about respecting the intricate dance of electricity and combustion that powers our vehicles, ensuring that every spark is in its right place.

  • Ethylen-Propylen-Dien-Kautschuk (EPDM)

  • Over time, piston oil seals may wear out or become damaged due to normal wear and tear, extreme temperatures, or poor maintenance practices. When this happens, oil leakage can occur, leading to decreased engine performance and potential damage to the engine.


  • One of the most notable developments was the introduction of ceramic spark plugs. These plugs are made from a high-tech ceramic material that is both durable and heat-resistant. This allows them to withstand higher temperatures and last longer than traditional metal spark plugs, leading to improved engine reliability and reduced maintenance costs.
  • 5. Replace the spark plug wires and ensure that they are properly connected to the distributor.

  • An oil seal is a type of mechanical seal used to prevent the leakage of oil from machinery components. The dimensions of an oil seal are usually specified in terms of its inner diameter, outer diameter, and thickness. For example, a 38x52x7 oil seal has an inner diameter of 38mm, an outer diameter of 52mm, and a thickness of 7mm.


  • • Rotational speed, etc.
  • Understanding these percentages is not only essential for engineers and technicians but also for end-users who rely on the seamless functioning of machinery. They highlight the delicate balance required in oil seal design and operation, emphasizing the need for precision, quality materials, and proper maintenance.

  • Aside from its performance benefits, Iridium Spark Plug also offers significant environmental advantages. The use of iridium reduces the need for other precious metals like platinum, which are often mined in environmentally harmful processes. This makes Iridium Spark Plug a more sustainable and environmentally friendly solution for the automotive industry.

  • Valve oil seals are typically made from a high-quality rubber or silicone material that is resistant to oil and high temperatures. They are designed to fit snugly around the valve stem and create a tight seal that prevents oil from leaking past the valve guide into the combustion chamber. This helps to ensure that the engine runs smoothly and efficiently.

  • Silicone rubber (VMQ)

  • 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.

  • Oil seals operate by creating a tight barrier between two moving or stationary parts, such as a shaft and housing, to prevent oil from escaping and contaminants from entering the system. This is essential for maintaining the efficiency and performance of the machinery, as well as preventing potential safety hazards.


  • Production seals of very common materials, oil - resistant sealing products adopt butyronitrile rubber.
  • Another important consideration when selecting a hub oil seal is its compatibility with the fluid being sealed

  • Installation

  • In the world of mechanical engineering, precision is everything. Every component, no matter how small, plays a crucial role in the overall functionality of a machine. A prime example of such an integral part is the 12x22x5 oil seal. This unassuming component ensures that lubricants stay where they are needed most and prevent contaminants from entering critical areas.
  • A small rubber gasket is essentially a seal designed to fill the gap between two surfaces to prevent leaks, ensure a tight fit, or cushion against vibration. Made from versatile materials like neoprene, silicone, or EPDM (ethylene propylene diene monomer), these gaskets are engineered to withstand a range of temperatures, pressures, and chemical exposures depending on their application.
