How to choose grease for automobile assembly reasonably

The choice of automobile assembly grease is very important, and the wrong choice will bring a lot of unnecessary trouble in the later stage. Most of the grease used in the car is used in the chassis, especially in the hub bearing, and the amount of grease used in other parts is less. So how can we get more suitable for our own car grease when we choose grease?

At present, most greases used in vehicles are soap-based greases, such as calcium based grease, lithium based grease, aluminum based grease and composite lithium based grease. They are made of lubricating oil plus thickening agent and some additives. The performance requirements of automobile assembly grease also have many, such as: water resistance, extreme pressure anti-wear, mechanical stability, oxidation stability, etc., these properties are must have, so that it can well ensure mechanical lubrication.

The cone entry of automobile assembly grease is also one of the reference elements, and the cone entry is what we usually call the hardness. Usually, we use the classification standards of the American Grease Institute (NLGI) to divide grease into nine grades, such as 000#, 00#, 0#, 1#, 2#, 3#, 4#, 5#, 6#, to indicate the degree of softness and hardness of grease. The lower the grade, the harder the grease.

In addition, we also consider the mechanical load and extreme pressure performance requirements. This can be improved by adding an extreme pressure antiwear agent to the grease. For example, some large trucks, seriously overloaded vehicles should choose the hub bearing extreme pressure, mechanical stability and other better grease.

The correct choice of grease can greatly improve the life of bearings and save unnecessary waste.
