The pressures required to deliver an NLGI grade 2 grease through Tubing and Feeders / Distributors are much higher than those used in systems for lubricating oils and grease belonging to lower NLGI grades 00 and 000. Pressures of 200 bars or more can occur, depending on the size of the system, tubing cross sections and lengths.

Obviously, cold temperature or W ratings are tested differently than regular SAE viscosity ratings. Simply put, these tests are done with a different temperature system. There is a scale for the W, or winter viscosity grades and, depending on which grade is selected, testing is done at different temperatures.See the Tables to the right below for more information.
Greases with a high consistency, i.e. stiff greases, are assigned high NLGI grades, while those with low consistency, i.e. soft greases, are assigned low NLGI grades. In rolling bearing applications, three consistency grades are recommended: The most common greases, used in normal bearing applications, have an NLGI grade of 2.

Explaining the NLGI System for Grading of Greases In general, grease up to NLGI grade 2 is used in Automatic Lubrication Systems. The pumpability of grease is influenced not only by its penetration but also, among ...
A: No. NLGI grade (named for the National Lubricating Grease Institute that developed the grading system), is primarily a function of the thickener used in the grease formulation. Meanwhile, the base oil(s) used in grease formulation determine what is known as the base-oil viscosity of the grease. The two characteristics are not directly linked.
Grinding Mill. XSM grinding mills vary from coarse grinding, medium grinding to micro fine grinding.Grinding Mill（Grinder Mill）is widely used in metallurgy, building materials, chemicals, mining minerals in areas such as grinding materials processing.The materials include line, calcite, barite, coal, gypsum, mica and bentonite powder.
This is a classic case of machine system development moving ahead of lubricant performance. However, two major developments can be traced from it, ﬁrst, the additive industry and second, the system of speciﬁcation and testing of lubricants as now organised by API, ACEA and ILSAC, Chapter 17.

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.
