Grease Viscosity and NLGI Number Grad

Grease Viscosity and NLGI Number Grades The ability of any particular grease to be handled by grease pumps, grease dispensers, and other components in a automated greasing system depends on the grease viscosity (thickness). Grease is a mixture consisting of a natural or synthetic oil base combined with thickeners and additives.

what grease to use for lubrication: NLGI numbers explained .

Common greases are in the range 1 through 3. Those with a NLGI No. of 000 to 1 are used in low viscosity applications. Grades 0, 1 and 2 are used in highly loaded gearing. Grades 1 through 4 are often used in rolling contact bearings. Greases with a higher number are firmer, tend to stay in place and are a good choice when leakage is a concern.
