Hebei Hankai rotary shaft seal
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.
