The most commonly used greases, such as those used in automotive bearings, would use a lubricant that is NLGI grade 2, which has the stiffness of peanut butter. Grades within this range can operate in a higher temperature range and at higher speeds than NLGI grades 000-0.
Is Polyrex em compatible with lithium?
Mobil Polyrex EM greases have been shown to be compatible with a number of ExxonMobil lithium complex greases, as well as competitive electric motor mineral polyurea products, as determined by the methodology of ASTM D6185.
What is the difference between EP 1 and EP 2 grease?
Grease Lithium EP is specially formulated to lubricate all sorts of equipment and mechanisms. Grease Lithium EP 1 will work very will in centralized systems and extreme pressure gears working at ambient temperatures. Grease Lithium EP 2 and 3 are well suited in heavy duty bearings and general industrial lubrication.
Is Nlgi the same as EP?
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 is lithium EP grease?
Valvoline Multipurpose Lithium EP 2 is a high-quality, high-performance, heavy-duty lithium thickened grease formulated with extreme additives and mineral base oil. Due to its distinct properties, Valvoline Multipurpose Lithium EP 2 is suitable to be used in heavy load bearings and unfavourable working conditions.
Are lithium and polyurea grease compatibility?
Lithium and polyurea greases cannot be mixed. “They can cause each one to lose their oil and dry out,” said Hamilton. The product loses the ability to lubricate.
How do you know if grease is compatible?
Greases are considered to be compatible if the following conditions are met:
- The dropping point of the mixture is not significantly lower than that of the individual greases.
- The mechanical stability of the mixture is within the range of consistency of the individual greases.
Is NLGI 2 grease lithium?
NLGI #2, Vegetable-based, Lithium 12 Hydroxy grease. Designed and developed to meet the US EPA 2013 Vessel General Permit (VGP) requirements.
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.
Can you mix lithium grease with regular grease?
But the two greases are incompatible. Lithium and polyurea greases cannot be mixed. “They can cause each one to lose their oil and dry out,” said Hamilton.
