LUBRICATING GREASE AND BEARING USING THE LUBRICATING GREASE

摘要

PROBLEM TO BE SOLVED: To provide a lubricating grease which adds little load to the environment if it is eluted into water.

SOLUTION: The lubricating grease contains a base oil being polyoxypropylene glyceryl ether and a density controlling powder. The grease contains a thickener which is lithium soap but may be something else. Because the grease contains the base oil being polyoxypropylene glyceryl ether, it sparingly dispersed in water and reduces the formation of an oil film. The contained density controlling powder can control the floating and sinking of the grease to or in water and facilitates its recovery or other treatments.
