- When it comes to maintaining the performance of your vehicle, one of the most important components to keep an eye on is the spark plug. The CMR5H spark plug is a popular choice among drivers due to its reliability and efficiency.
- Felt seals are made from felted wool or synthetic materials and are used in applications where low-speed and low-pressure sealing is required. These seals are cost-effective and easy to install, making them suitable for a wide range of industrial applications.
- However, the importance of the small rubber gasket is often overlooked until a problem arises. When a gasket fails, it can result in a domino effect of issues ranging from minor inconveniences to catastrophic system failures. Thus, regular inspection and prompt replacement are crucial to avoid potentially disastrous consequences.
Apply gasket sealant to the engine flange and refit the cover. Tighten the fixings but do not overtighten them.
Most oil seals consist of some basic elements that configure their structure, such as the sealing element, the metal case, and the spring:
Oil seals are widely used as sealing devices for machines.
JTEKT's oil seals are described in our catalog, Oil Seals & O-Rings.
However, the catalog uses a large number of technical terms and is very long, so many people seem to have trouble handling it.
Therefore, this series of columns will summarize the following in order:
• The structure, functions, and types of oil seals
• How to select the right oil seal
• Handling of seals, and causes and countermeasures for oil seal failure
Silicone compounds or “VMQ” offers a wide range of traditional operating temperatures starting at -60°C to 200°C (-140°F to 392°F).

• Rotational speed
• Oil viscosity, etc.
In addition to carbon buildup and oil leakage, black spark plugs can also be caused by overheating. If the engine is running too hot, it can cause the electrodes on the spark plugs to wear down and become coated in carbon deposits. This can lead to poor engine performance and reduced fuel efficiency. It is important to monitor the engine temperature and address any overheating issues promptly to prevent damage to the spark plugs.
Oil seals are often called grease, fluid, or dirt seals. These seals close spaces between stationary and moving components in mechanical equipment. Oil seals are designed to prevent the escape of lubricant. They also block contaminants from entering machinery. This is especially important in severe environments where heat and foreign objects may be frequently present. They also prevent the mixing of different mediums like lubricating oil and water.
