The design and material selection of high pressure shaft seals are crucial for their performance
high pressure shaft seals. Advanced materials such as polytetrafluoroethylene (PTFE) and silicone rubber are frequently employed due to their excellent resistance to chemicals, temperature fluctuations, and wear. Furthermore, the geometry of the seal must be optimized to withstand the extreme forces exerted by high-pressure fluids while minimizing friction and heat generation.

Moreover, the oil seal acts as a barrier against external elements like dust, water, and road debris. These substances can cause corrosion, wear, and even damage to the sensitive components inside the hub, potentially causing significant performance issues or even complete breakdowns These substances can cause corrosion, wear, and even damage to the sensitive components inside the hub, potentially causing significant performance issues or even complete breakdowns

A worn-out or damaged seal kit can lead to fluid leaks, which can hinder the efficiency of the hydraulic jack. It can also result in the jack not being able to lift heavy objects properly, putting the user at risk of accidents. Therefore, it is crucial to regularly inspect the seal kit and replace it if necessary to ensure the proper functioning of the hydraulic jack.
Metal oil seals are available in a variety of designs and configurations to suit different applications
. Some seals are designed to withstand higher temperatures and pressures, while others are specifically engineered for use in specific types of machinery or equipment. This versatility makes metal oil seals a versatile and reliable solution for a wide range of sealing requirements.The percentage of an oil seal refers to its ability to effectively prevent leakage. A higher percentage indicates a better sealing capacity, with 100% being the ideal value. However, in reality, achieving a perfect seal is often challenging. Therefore, oil seals with percentages ranging from 25% to 35% are commonly used in applications where a high level of sealing performance is required.
