- The performance of an oil seal is crucial in ensuring the efficiency and longevity of the equipment in which it is used. A high-quality oil seal can withstand high temperatures, pressure, and speed, while maintaining a tight seal to prevent leaks. This is especially important in industries such as automotive, aerospace, and manufacturing, where even a small leak can lead to significant damage and downtime.
- The dimensions 35x50x8 denote the primary characteristics of this particular oil seal. The first two numbers, 35 and 50, represent the outer diameter and the inner diameter respectively, specifying the sizes at which it can effectively function. The final number, 8, indicates the thickness or the cross-sectional dimension of the seal. This design allows for a snug fit in various applications, creating a robust barrier against fluid escape and foreign particle intrusion.
In conclusion, engine oil seals, power steering oil seals, and motor oil seals are essential components in automotive systems, contributing to the efficiency, performance, and reliability of the vehicle. Understanding the significance of these seals and their proper maintenance is crucial for optimizing the performance and longevity of the vehicle.
- Mechanical seals are another type of oil seal that relies on mechanical components to create a seal
They are typically made from elastomers such as rubber or silicone and consist of an outer metal case with a sealing lip on the inner side.

Developments and issues
The sealing lip is always made of a rubber or synthetic material. For oil seals with a rubber outer case (R, RST, GR, GRST), the rubber quality of the sealing lip and the outer case are the same.

Pick the proper seal for your bearing with the NBC bearing.


Car iridium spark plugs are a popular choice for modern vehicles due to their durability, high melting point, and superior conductivity. Iridium spark plugs offer enhanced performance and longevity compared to traditional copper or platinum plugs. The use of iridium in the electrode design allows for a smaller center electrode, promoting more efficient combustion and improved engine performance. Car iridium spark plugs are known for their ability to maintain optimal engine performance over an extended service life.
