  • From this kind of standard immersion testing, one would expect that bisphenol-cured VDF/HFP/TFE fluoroelastomers would not give good service life as oil seals. Similar tests with other elastomers, such as HNBR, silicone, and acrylic rubbers, show less loss of elongation. However, it is found that, in actual service, FKM shaft seals6 have much longer service life than seals of the other elastomers. In a Japanese study of FKM lip seals, rear crankshaft seals from high-mileage automobiles (70,000–280,000 mi ie, 110,000–450,000 km) were collected and examined. No serious oil leakage was found when the seals were removed from the engines. Some deposits were found around the seal lip and on the garter spring holding the lip against the shaft. No surface cracks were found on the seal lip, and only minor crazing on the crankcase side of the flexure portion of the seal in some samples. The seal compositions were not noted, but most were probably VDF/HFP/TFE elastomers with 68–69% fluorine content.

  • White rubber gaskets are predominantly made from synthetic polymers or natural rubber, offering an excellent balance between cost-effectiveness and durability. Their pliability allows them to conform to irregular surfaces, creating a tight seal that prevents liquid or gaseous substances from escaping or entering where they're not wanted. This property is critical in pipeline systems transporting water, gas, or chemicals, where leaks could lead to environmental damage or safety concerns.

  • Is the seal you need not available from one of our standard ranges? No problem. We design and supply seals in any material, size and quantity - from very small to very large volumes.

  • In addition to protecting the wheel bearings from contamination, wheel oil seals also help to prevent oil leakage from the wheel hub. This is particularly important in heavy-duty vehicles such as trucks and buses, where the wheels are subjected to high loads and harsh operating conditions. A leaking wheel oil seal can result in oil loss, which can lead to inadequate lubrication of the wheel bearings and potentially cause serious damage to the wheel assembly.
  • In the vast world of manufacturing, there are countless components that work tirelessly behind the scenes to ensure the smooth operation of machinery. One such unsung hero is the humble round gasket, a simple yet essential part that plays a crucial role in sealing and preventing leaks in various industrial processes.
  • Oil seals are an essential component of many industrial machines and equipment. They play a crucial role in preventing oil leaks, protecting bearings and other crucial parts from contamination, and ensuring the overall smooth operation of the machinery. One popular and widely-used size of oil seal is the 75x100x10 model.

  • Replace the sump drain plug tightly and refill the engine with the right amount and grade of oil.

  • 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

  • Car Engine Oil Seal: Importance and Impact

  • The failure of an oil seal can result in oil leaks, which not only waste valuable lubricant but also pose environmental risks. Moreover, the absence of a proper seal can allow dirt and other debris to infiltrate the system, causing accelerated wear on moving parts. In some cases, the loss of lubrication can cause overheating and potentially lead to fires or explosions, especially in high-pressure applications.
  • Wear and oil loss remains two of the most frequent signs of engine seal failure and, if not paid attention to, it can give rise to a breakdown in the vehicle’s system. Regular maintenance and routine oil changes minimize the issues associated with oil seals and potential oil loss. 

  • Spring The spring supplements the tightening force (i.e., the lip radial load) to ensure enhanced sealing performance and tight contact between the shaft and the sealing edge.The spring also prevents the deterioration of main lip sealing performance caused by high heat or other such factors.

  • Moreover, the importance of oil seals extends beyond mere physical protection. They contribute to environmental stewardship by preventing oil spills that could contaminate ecosystems They contribute to environmental stewardship by preventing oil spills that could contaminate ecosystems They contribute to environmental stewardship by preventing oil spills that could contaminate ecosystems They contribute to environmental stewardship by preventing oil spills that could contaminate ecosystemsframework oil seal. From an economic standpoint, their use reduces maintenance costs associated with frequent oil changes and part replacements due to contamination.

  • Another common cause of black spark plugs is engine oil leakage. If oil is leaking into the combustion chamber, it can cause the spark plugs to become fouled with a black, sooty residue. This can lead to misfires and engine hesitation, as well as increased fuel consumption. It is important to address any oil leaks promptly and replace the spark plugs if necessary.


  • 2. Axial shaft seals These seals prevent oil leakage along the axial direction of a shaft. They are commonly used in hydraulic cylinders, pneumatic actuators, and other applications where axial movement is present.
  • /We just discovered that one of the seals on our pumping system is leaking. Do you have any ideas as to what could have caused this, and can you offer some advice for selecting a good seal?
