When selecting gear grease, attention should be paid to the base oils used in the manufacture of the grease and its viscosity grade. Most gearboxes tend to be highly loaded and therefore require a lot of lubricant to protect the internal surfaces of the machine. In this case, the viscosity should not be low to ensure a good lubricating film. Another point to be aware of are extreme pressure additives. These additives can be chemically aggressive and can lead to chemical corrosion of machine surfaces. This is why Copmlex Ag 1500 is the most common in equipment parts. For this reason, polyurea greases are commonly used for bearing lubrication. The biggest factor when choosing a lubricating grease is to make sure that all other components of the grease are compatible with the requirements of the machine. Once these are balanced, you can be sure that you have chosen the most suitable lubricant for your application.
