Hydraulic cylinders operate on the principle of Pascal's Law, which states that pressure applied to a confined fluid is transmitted undiminished throughout the liquid. Engine hoists typically use these cylinders to lift engines and other heavy components by converting hydraulic pressure into linear motion. However, constant use can lead to issues such as leaks, reduced lifting power, and eventually, cylinder failure.

2. Seals and Gaskets Similar to O-rings, seals and gaskets prevent fluid escape and ensure that all components function smoothly together.

Once the jack is reassembled, refill it with hydraulic oil and test it to make sure it is functioning properly. If everything looks good, you can now use your jack with confidence, knowing that it has been properly maintained and repaired.

One of the key challenges in designing high temperature shaft seals is the ability to withstand extreme heat without compromising performance. As temperatures increase, traditional seals made from rubber or elastomers may degrade and lose their sealing capabilities. Therefore, specialized materials such as thermoplastics, ceramics, or metal alloys are often used to manufacture high temperature shaft seals.
