Lithium-based grease has a dropping point at 190 to 220 °C (374 to 428 °F). However the maximum usable temperature for lithium-based grease is 120 °C. The amount of grease in a sample can be determined in a laboratory by extraction with a solvent followed by e.g. gravimetric determination.
Lithium grease adheres particularly well to metal, is non-corrosive, may be used under heavy loads, and exhibits good temperature tolerance. It has a dropping point of 190 to 220 °C (370 to 430 °F) and resists moisture, so it is commonly used as lubricant in household products, such as electric garage doors, as well as in automotive ...
This statement: "Grease-lubricated bearings have greater frictional characteristics at the beginning of operation, causing a temperature rise which tends to melt the grease and give the effect of an oil-lubricated bearing" seems to contradict this one: "Lithium based grease has a drip temperature at 350° to 400°F".

Lithium 12-hydroxystearate exhibits high oxidation stability and a dropping point up to around 200 °C. Most greases used today in motor vehicles, aircraft, and heavy machinery contain lithium stearates, mainly lithium 12-hydroxystearate. [1] Greases can be made with the addition of several different metallic soaps.
The test grease is inserted into the container and the plunger is stroked 60 times while the test apparatus and grease are maintained at a temperature of 25 °C. Once worked, the grease is placed in a penetration test apparatus. This apparatus consists of a container, a specially-configured cone and a dial indicator. The container is filled ...
A joint battery venture of Toyota Motor Corp and Panasonic Corp on Tuesday said it will produce lithium-ion batteries for hybrid cars at a plant in Western Japan from 2022 to meet growing demand ...
The measure of the consistency of a lubricating grease is commonly expressed by its NLGI consistency number, defined by the NLGI in the “standard classification of lubricating grease”. The NLGI consistency number is used in several standards: ASTM D4950 , SAE J310 and ISO 6743-9 “lubricants, industrial oils and related products (class L ...
