  • Oil seals are always exposed to a lot of chemicals, both mild and harsh chemicals. The seals react by showing some signs like cracks, blisters, and discoloration especially when the chemical is harsh. This clearly shows that the chemical is not compatible with the seal, which goes as far as affecting its cross-link density (increase or decrease). When the cross-link density increases, the seal material becomes harder, but when it decreases, the seal material becomes softer.

  • Another trend in front hub oil seal technology is the use of smart sensors and monitoring systems. These devices can detect changes in pressure, temperature, or vibration that may indicate a problem with the seal or the hub itself These devices can detect changes in pressure, temperature, or vibration that may indicate a problem with the seal or the hub itself These devices can detect changes in pressure, temperature, or vibration that may indicate a problem with the seal or the hub itself These devices can detect changes in pressure, temperature, or vibration that may indicate a problem with the seal or the hub itselffront hub oil seal.

In this article, we will explore the benefits of natural rubber gaskets and the key factors to consider when choosing the right gasket for your specific application.


  • Oil seals serve as a barrier, preventing oil from escaping the confines of the machinery while also stopping contaminants from entering
  • An oil seal, also known as a shaft seal or dirt seal, prevents lubricants such as oil and grease from escaping along a rotating shaft. Oil seals are an important component in preventing leaks and contaminants from clogging various engines, pumps, and pipelines.
    Installing and replacing oil seals can be a daunting task. But with the right knowledge, the results can be good. Here are 8 tips to guide you on what to look for when working with oil seals. Read on for more information.

  • 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.

  • 1. Temperature resistance High temperature rubber gaskets can withstand high temperatures, making them suitable for use in harsh environments. The temperature resistance of these gaskets depends on the type of rubber used, with silicone rubber being the most。
  • Upgrading to high-performance spark plugs can also improve your vehicle's overall performance. High-performance spark plugs offer better ignition capabilities, resulting in improved fuel efficiency, horsepower, and acceleration. While they may come at a higher cost, the benefits of upgraded spark plugs can be well worth the investment for drivers seeking enhanced performance.
  • Why use NOK-CN factory-made oil seals?

  • Oil seals are made from multiple compounds and materials. Some of the oldest, still in use today, are leather and felt compounds. The trend in mass production, however, has seen a move towards synthetic rubber or elastomers. Nitrile is by far the most popular material but developments in PTFE have created a surge of interest in buyers needing seals for high-speed shaft rotation applications. Viton is taking over from the polyacrylic and silicone, as it works better in high-temperature applications and has a high-resistance to abrasion and harmful chemicals.
