What is the difference between NLGI 2 and 3?
It is classified according to a scale developed by the NLGI (National Lubricating Grease Institute). The softer the grease, the lower the number….Consistency.
| NLGI number | ASTM worked penetration (10–1 mm) | Appearance at room temperature |
|---|---|---|
| 1 | 310–340 | very soft |
| 2 | 265–295 | soft |
| 3 | 220–250 | medium hard |
| 4 | 175–205 | hard |
Are all NLGI 2 greases the same?
This tells us two things, EP 2 grease is a NLGI Grade 2 and it is fortified with Extreme Pressure (EP) additives. This tells us nothing else about the thickener type, base oil type or viscosity of the base oil. The correct NLGI grade is an important consideration because not all grease applications are the same.
What does NLGI stand for in grease?
the National Lubricating Grease Institute
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).
What grease is best for bearings?
- Editor’s Choice: Valvoline Full Synthetic Grease.
- Lucas Oil X-Tra Heavy Duty Grease.
- Lucas Oil Red ‘N’ Tacky Grease.
- Mag 1 High-Temp Wheel Bearing Grease.
- Mobil 1 Synthetic Grease.

Is NLGI 2 grease good for wheel bearings?
The grease used for most wheel bearings should meet the NLGI GC-LB requirements or the SAE J2695 requirements. Most wheel bearings require an NLGI 2 grade grease, while some sealed hub units require an NLGI 00 grade semi-fluid product.
What do NLGI ratings mean?
The NLGI number is a measure of the grease’s consistency as indicated by its worked penetration value. The penetration test measures how deep a standard cone falls into a grease sample in the tenths of millimeters. Each NLGI grade corresponds to a specific worked penetration value range.
Does the color of grease mean anything?
One thing we are sure of, however – color does not denote a particular type of grease, whether it is red, green, blue or yellow. The color is simply a dye added by manufacturers for marketing purposes, to more easily distinguish the different greases in their product lines.
What is No 2 lithium grease?
Offering excellent lubricity, shear stability, and thermal resistance, lithium soaps are the most commonly used thickeners. Grade 2 is a fairly standard grease, for use in normal bearing applications. It has a consistency similar to peanut butter. The penetration range at 77°F (25°C) is 265 to 295.
Is red and tacky grease good for wheel bearings?
Red N Tacky has a red Lithium Complex Base that is red in color, forming an effective seal to minimize bearing and hub contamination, with resistance to water washout on boat trailers. This item comes in a 14.5 oz tube that will fit into any standard size grease gun.
