Hebei Hankai custom oil seals
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.

Another category of meat preservatives includes natural options such as salt, sugar, and vinegar. Salt has been used for centuries due to its effectiveness in drawing moisture out of meat, creating an inhospitable environment for bacteria. Sugar, often used in conjunction with curing processes, can also extend shelf life while enhancing flavor. Vinegar and similar acids can lower pH levels, further inhibiting microbial growth. These natural preservatives appeal to health-conscious consumers who prefer minimally processed foods and are wary of synthetic additives.
