NLGI consistency number - Wikipedia
The NLGI consistency number (sometimes called “NLGI grade”) expresses a measure of the relative hardness of a grease used for lubrication, as specified by the standard classification of lubricating grease established by the National Lubricating Grease Institute (NLGI). Reproduced in standards … See more NLGI's classification defines nine grades, each associated to a range of ASTM worked penetration values, measured using the test defined by standard ASTM D217 “cone penetration of lubricating grease”. This … See more The following table shows the NLGI classification and compares each grade with household products of similar consistency. Common greases … See more WebConsistency Under the mechanical stresses of an application, some lubricating oil is “squeezed” out of the grease thickener matrix and delivered to the lubrication points, providing the lubrication, film formation, and wear prevention that is required to ensure optimum equipment performance. irish jewellery nz
