What is the purpose of lubrication? One of the most important tasks is of course lubrication. Lubrication reduces wear and friction between two components. This ensures that the various surfaces last longer. Another advantage is the cooling effect on the heat generated by operation. As a side effect, lubricants also have a cleaning effect - they prevent the deposit of substances from the production process.
Due to their multifunctional properties and the fact that they fulfill these numerous tasks, lubricants are indispensable in the automotive and industrial sectors! They protect the respective machines and components from wear, dirt and corrosion and thus prevent costly repairs and new purchases.

What is the difference between grease and oil lubricants?
When you add thickeners to oil, you get greases. Physical state: At room temperature, greases are usually solid, while oils are usually liquid.
Conversion: All oils can be converted into fats, but not all fats are made from oils.

Every grease has certain characteristics that are needed to categorize it.
The most important characteristics are:
▶️ Base oil viscosity
▶️ Dropping point
▶️ Operating temperature
▶️ Speed characteristic
▶️ Consistency
▶️ NLGI class
▶️ Four-ball test

Compared to lubricating oils, greases consist of three main components: base oil, thickener and additives.
These components have a major influence on the classification into an NLGI grade. The base oil can make up to 95% of the grease and serves to reduce friction between moving machine parts.
Viscosity and temperature resistance are important factors in the properties of the grease.
Thickeners complement the base oil and form the structure of the grease, which is called the matrix. This matrix holds the oil together and is only pressed out of the matrix when used. The hardness of the matrix varies depending on the NLGI grade.
It is important not to mix greases with different thickeners as this can cause damage to the machine.
Additives improve the lubricity of the oil and provide additional rust protection.

Lubricating greases are divided into nine different classes according to their consistency using the National Lubricating Grease Institute (NLGI) scale. The classification is based on a test procedure in which the penetration depth of a cone into a lubricating grease is measured in tenths of a millimeter.
The consistency of a lubricating grease is recommended by the manufacturers in the operating instructions and has a decisive influence on the application. Lubricating greases in classes 000 to 0 are so-called fluid greases. These are suitable for central lubrication systems due to their good flow properties. Firmer lubricating greases, such as NLGI class 3, are used to adhere to the lubrication point or to seal it.
The DLS products are suitable for lubricants in NLGI classes 0 to 2.

Can grease or oil go bad? Yes!
As surprising as it may sound, lubricants can also exceed their shelf life.
A good grease or oil can be recognized by its clear, defined and homogeneous structure. The consistency and appearance are uniform and unchanged everywhere.
If a grease or oil goes bad, the structure and appearance change. The components of the lubricant separate from each other. It becomes "lumpy" or "mushy".
DLS recommends a regular visual inspection of the lubricant.
This usually has a shelf life of between 18-24 months.
