Lubricating grease compositions
摘要:
Use of a lubricating grease composition in a mass flywheel application wherein the lubricating grease composition comprises: (i) a base oil having a density in the range of from 800 to 1000 Kg/m3; and (ii) a urea compound having a density in the range of from 850 to 1050 Kg/m3; wherein the difference in the densities of the base oil (i) and the urea compound (ii) is less than 50 Kg/m3. The lubricating grease compositions according to the present invention are particularly useful for reducing oil bleeding and for improving shear stability properties in a dual mass flywheel application.
