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.
Which grease is best for motor?
The preferred thickener for most electric motors is polyurea. However, aluminum complex, lithium complex or calcium sulfonate thickeners are also good options.
What is nlgi2 grease?
NLGI Grade 2 grease is a multipurpose grease for oxygen and harsh chemicals in industrial applications. Grade 2 grease is an excellent lubricant for plain and antifriction bearings operating under moderate load and at medium speeds.
Can you mix polyurea and lithium grease?
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.
What kind of grease is used in electric motors?
NLGI 2 grade grease
areas to be lubricated. A NLGI 2 grade grease is the most commonly used in electric motor applications.
What happens if you mix grease types?
When two incompatible greases are mixed, one of two things generally happens: the mixture hardens and will not release any of the oil or the mixture softens and releases all of the oil. In either case, the end result is basically the same; there is effectively no lubrication.
Can you mix lithium and aluminum grease?
Testing by major grease and bearing manufacturers reveals some grease types are incompatible. Lithium 12-hydroxy is incompatible with aluminum complex and calcium complex thickeners, but moderately compatible with calcium sulfonate, a typical marine grease thickener.
What type of grease should I use for electric motors?
A NLGI 2 grade grease is the most commonly used in electric motor applications. ASTM D 3336 oxidation life. require a grease with an EP additive. Dropping Point: The dropping point gives an indication of the temperature at which the grease will melt or the oil will separate from the thickener.
