- A wheel hub oil seal, also known as a bearing seal, is a critical sealing device located between the wheel hub and the brake drum or disc. Its primary function is to prevent the ingress of dirt, water, and other contaminants into the wheel bearing while retaining the lubricating oil inside. This dual-purpose operation is crucial for maintaining optimal performance and preventing premature wear and tear.
- One of the most common types of spark plugs is the copper-core spark plug. These plugs are known for their excellent conductivity and heat dissipation, making them a popular choice among automotive enthusiasts. Copper-core spark plugs are also relatively inexpensive compared to other types, making them a cost-effective option for those on a budget.
- Over time, due to constant exposure to high temperatures and pressure, oil gaskets can wear out or become damaged. Signs of a failing oil gasket include oil leaks under the vehicle, engine oil contamination, or an engine that runs low on oil despite regular topping up. When these signs appear, it's crucial to have the gasket inspected or replaced promptly to avoid more severe problems.
Why is mechanical seal important in this situation? It is because the rotating shaft has to move in a wet environment, but there should not be the leakage of pressurized fluid. Hence, the role of a seal is quite critical.

Why use NOK-CN factory-made oil seals?


Among the most common causes of oil seal failure are:
The basic principle of sealing is straightforward – the flexible lip is held against the rotating part (usually the shaft) whilst the casing (or O.D.) is pressed into the housing or bore and holds the seal in place. The sealing lip needs some form of lubrication to avoid overheating and is usually energized by means of a garter spring.

Oil seals, also referred to as shaft seals, are widely used to prevent the leakage of medium (such as oils and grease) along a rotating shaft. This leak prevention is primarily achieved by the sealing element which can be made from a wide range of materials that are chosen according to each application. They are commonly used in gearboxes, hydraulic cylinders, and related components.

Regular maintenance of the spark plug ignition coil is essential to ensure optimal engine performance. This includes checking for any signs of wear or damage, such as cracks in the casing or corrosion on the connectors. It is also important to replace the ignition coil as part of the recommended maintenance schedule to prevent any potential issues from arising.
