In grease, NLGI refers to the National Lubricating Grease Institute, the organization that developed a standardized numerical scale to classify the consistency or thickness of grease.
-
It's a measure of hardness:
The NLGI grade indicates the relative hardness of the grease, based on a standard test called worked penetration.
-
The scale:
The scale ranges from 000 (very soft and fluid-like) to 6 (very hard and block-like).
-
Common grades:
NLGI 2 is a common and versatile grade, suitable for many automotive applications where the grease needs to stay in place.
Why It's Important
-
Proper lubrication:
Choosing the correct NLGI grade ensures the grease can effectively migrate into the areas requiring lubrication without migrating away from those areas.
-
Application suitability:
It's a critical factor for specifying the correct grease for a particular application, complementing other performance properties like stability and viscosity.
Common Uses for LUBRATEX NLGI #2 Grease
-
Automotive: It's the standard for lubricating wheel bearings, CV joints, and other chassis components in cars and trucks.
-
Industrial: Used in various industries, including manufacturing, construction, and mining, for heavy-duty equipment.
-
Agricultural: Found in farm machinery like tractors and combines.
-
Marine: Lubricates components on boats and ships.
-
High-Speed & High-Temperature: Suitable for electric motors and other high-speed, high-temperature parts where soap-base greases might not be suitable.
-
General Machinery: Applicable to pumps, fans, conveyors, and other industrial equipment.
