Chinese spark plug manufacturers adhere to stringent quality control measures to ensure that their products meet industry standards and specifications. Advanced manufacturing processes, precision engineering, and rigorous testing protocols are employed to produce high-quality spark plugs that deliver reliable performance and durability. Manufacturers prioritize material quality, heat resistance, and electrode design to optimize the spark plug's ignition capabilities and longevity.
What are bearing isolators?

- The '6%' in the seal's description usually refers to the lip's thickness or the percentage of the seal's cross-section that comes into contact with the shaft. This percentage contributes to the seal's effectiveness in maintaining a tight barrier against oil escape. A higher percentage typically indicates better sealing capabilities, but it also increases friction, which may affect the longevity of the seal and the rotating component it contacts.
- Relatively less maintenance and cleaning are required. It makes mechanical seals cost-effective.



For many bearings, a good bearing seal is essential. Bearing seals perform a dual function by keeping lubricants from leaking out while preventing impurities from entering your parts. Both procedures can help your bearings last longer, but choosing the proper seals for your components is critical. Different types of bearing seals include:
ERIKS type M (type B according to the DIN standard) has a single metal casing and rubber sealing lip. Since the casing is made of metal, it must be fitted in a well-finished, undamaged groove. Large volumes of oil seals with metal casings are often cheaper, which is why they are often used as original equipment in machines. However, if an oil seal has to be replaced, types with a rubber exterior (type R or RST) are easier to fit. Type MST is similar to M and commonly used. The difference is the dust lip in the MST oil seal that prevents dust and dirt reaching the sealing lip, and extends its service life in dusty environments.
Regular inspection and maintenance of spark plug wires and spark plugs are essential to identify signs of wear, damage, or deterioration. Proper replacement of worn or fouled spark plug wires and spark plugs is crucial for maintaining the efficiency and reliability of the ignition system. Adhering to recommended service intervals and using high-quality replacement components are essential for optimizing the performance and longevity of the vehicle's ignition system.
It is quite common for a groove to develop at the sealing lip at some point due to long-term use. As a result, the new oil seal no longer fits and seals properly. It is not strictly necessary to replace or repair the entire shaft. Take a closer look at the dimensions first. It may be possible to fit with a slightly narrower or wider oil seal next to the groove. Alternatively, using the Speedi-Sleeve repair kit, repair the running surface under the seal.
