Hebei Hankai custom made oil seals
One of the critical challenges in hydraulic seal design is ensuring that they maintain their integrity under varying operating conditions. High pressure and temperature fluctuations can lead to wear and tear, potentially compromising the seal's effectiveness. Therefore, manufacturers often incorporate design features that enhance durability, such as grooves and contours that improve sealing performance. Regular maintenance and inspection are also essential to identify signs of wear or degradation, allowing for timely replacement and preventing costly downtime.


1. Automotive Industry In vehicles, oil seals are crucial for various components, including the engine, transmission, and differential. The 20x35x7 oil seal can effectively prevent engine oil from leaking out, which is essential for maintaining lubrication and preventing damage to engine parts.

Oil seals work by creating a tight seal around the rotating shaft. This prevents oil and other fluids from escaping while allowing the shaft to rotate smoothly. The seal is usually made up of a lip that fits snugly against the shaft, preventing any leaks from occurring. Some oil seals also have additional features, such as springs or gaskets, to provide extra support and ensure a secure fit.
