Hebei Hankai high pressure seal

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.

Wiper oil seals often feature a unique design that includes a lip that contacts the shaft or surface it is sealing against. This lip creates a dynamic seal that adapts to the movement of the shaft, maintaining a tight enclosure even as the equipment operates. The design often includes an additional wiper or dust lip, which helps remove contaminants that come into contact with the seal, further enhancing its protective capabilities.
