What grease is compatible with Polyrex em?
ExxonMobil lithium complex greases
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. For specific questions about grease compatibility, contact your Mobil representative.
What are the different grades of grease?
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. The most commonly used grease is NLGI #2.
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 EP2 grease?
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.
What is the most important grease specification?
The most important property of any lubricant is viscosity. A common mistake when selecting a grease is to confuse the grease consistency with the base oil viscosity. Because the majority of grease-lubricated applications are element bearings, one should consider viscosity selection for those applications.
What is No 2 grease?
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.
