The differences between lubricating greases are dictated by factors such as the thickness of the grease. This is referred to as the NLGI class. Thicknesses are specified as a number from 0 to 3, with an NLGI 0 grease being thinner than an NLGI 2 grease. Central lubrication systems require a thinner grease for easier pumping, which could be an NLGI 00 or even an NLGI 000 grease. These greases are thinner and sometimes appear liquid in consistency.
Aside from the thickness of the grease, greases also differ in terms of their make-up. A lubricating grease consists of a thickener, basic fluid, and additives. The thickener determines the structure of the grease. Examples of thickeners include lithium, calcium, calcium sulphonate, and aluminium. The different structures relate to factors such as temperature, mechanical stability, and resistance to water.
Working out which lubricating grease best matches your application can sometimes be tricky. Lubricating a ball bearing, for example, can vary if the bearing is exposed to extreme conditions.
