Which grease is the best?

Which grease is the best? Grease is mainly used to lubricate and seal the friction parts of machinery, and it is mainly made of mineral oil (or synthetic lubricating oil) and thickeners. The following grease manufacturers introduce its functions in detail: Most greases used for lubrication are called anti-friction greases. Antifriction grease mainly plays the role of reducing mechanical friction and preventing mechanical wear. At the same time, it also plays a protective role in preventing metal corrosion and sealing and dustproofing. There are some greases that are primarily used to prevent metal from rusting or corroding, called protective greases. For example, there are a few greases such as industrial petroleum jelly that are specially used for sealing, called sealing greases, such as thread grease. Grease is mostly a semi-solid substance with unique fluidity.
The working principle of grease is that the thickener keeps the oil in the position that needs lubrication. When there is a load, the thickener releases the oil to lubricate.
At normal temperature and stationary state, it is like a solid that can maintain its shape without flowing and adhere to metal without slipping off. It can flow like a liquid at high temperatures or when subjected to external forces exceeding a certain limit. When grease is sheared by moving parts in machinery, it can flow and lubricate to reduce friction and wear between moving surfaces.
The above is an introduction to grease, and it can return to a certain consistency when the shearing action stops. The special fluidity of grease determines that it can be lubricated in parts that are not suitable for lubricating oil. In addition, because it is a semi-solid substance, its sealing and protective effects are better than lubricating oil.
