grease types and grades pdf

What makes a good grease? (page 1/2) There isn’t just one “good grease”. There are lots of different types, each one suited for a different application. So the most important thing is to identify the best properties for a specific application. The most important properties are listed below. Grease consistency NLGI grade. The consistency of a material is how much it resists deformation
