What are the different grades of grease?
What are the different grades of grease?
Grease Properties Greases are classified into nine consistency grades (000, 00, 0, 1, 2, 3, 4, 5, 6) established by the National Lubrication and Grease Institute (NLGI). NLGI #000 greases are nearly fluid, while NLGI #6 greases are nearly solid.
What is the difference between EP 1 and ep2 grease?
Mobilux EP 0 and 1 are suitable for centralised systems. Mobilux EP 2 are general-purpose greases. The recommended operating temperature range is from -20ºC to 130ºC, but they may be used at higher temperatures if the lubrication frequency is increased accordingly.
What does the NLGI number of a grease indicate?
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.
What grease is used in SKF bearings?
The most common greases, used in normal bearing applications, have an NLGI grade of 2. Low consistency rolling bearing greases, classified as NLGI 1 greases, are preferred for low ambient temperatures and oscillating applications.
What does DIN 51502 mean?
DIN 51502 : Designation of lubricants and marking of lubricant containers, equipment and lubricating points.
What do grease numbers mean?
The NLGI consistency number (sometimes called “NLGI grade”) expresses a measure of the relative hardness of a grease used for lubrication. The higher the NLGI number, the firmer/thicker the grease. The NLGI consistency number alone is not sufficient for specifying the grease required by a particular application.
What is the viscosity of EP2 grease?
Property
| Property | |
|---|---|
| Thickener Type | Lithium |
| Base Oil Viscosity of Greases @ 40 C, mm2/s, AMS 1697 | 150 |
| Color, Visual | BROWN |
| Dropping Point, °C, ASTM D2265 | 190 |
What is the difference between NLGI 1 and NLGI 2 grease?
NLGI #1 Grease versus NLGI #2 Grease Less thickener makes a #1 grease more tractable and slippery, while #2 grease has more thickener, making it stiffer and great for all-purpose applications.
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 |
Which grease is best for bearings?
Lithium based greases are very popular as bearing grease due to their water resistance and performance characteristics in both high and low temperatures. Greases comprised of synthetic lubricating fluids perform well in extreme low and high temperature ranges.
What is the difference between regular grease and lithium grease?
The main difference that exists between standard lubricating grease and lithium grease is that standard grease is often used in industrial settings and lithium grease is primarily used in domestic settings.
Is ep2 and NLGI 2 the same?
We are all familiar with “EP 2” grease. 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.
What would NLGI 2 GC grease be recommended for?
wheel bearings
NLGI #2 consistency greases are commonly recommended, but NLGI #1 or #3 grades may also be recommended. GC – Service typical of wheel bearings operating in passenger cars, trucks, and other vehicles under mild to severe duty.
What is high-speed grease?
High-speed greases are formulated with special thickeners and oils allowing them to approach the functionality of oil while keeping the sealing properties required in this type of mechanism. One of the parameters to take into account is the speed factor: NDm of the bearing to be lubricated.
