The invention discloses a lubricating grease with thixotropy and a preparation method thereof. The lubricating grease comprises a polyurea/high base number calcium sulfonate composite thickener, colloidally dispersed calcium carbonate solid particles in the form of calcite, a calcium borate or calcium borate composite, and a calcium soap of fatty acid having 12 to 24 carbon atoms. The above components are uniformly dispersed in an oil phase medium. The content of high base number calcium sulfonate in the lubricating grease is less than 22 wt %.

A method of lubricating a bearing, a bearing, and a lubricant with high thermal conductivity including a base oil, a polymeric thickener, and thermally conductive powder particles. The lubricant is, at atmospheric pressure, liquid above a transition temperature and a gel below said transition temperature.

The present disclosure relates to an automotive slide member including a first slide portion having a first lubricant applied between first portions of a first friction slide mechanism, and a second slide portion having a second lubricant applied between second portions of a second friction slide mechanism. The first slide portion is arranged at a part to be touched by an operator who attaches the automotive slide member to an automobile or a user of the automobile. The second slide portion is arranged at a part that is not touched by the operator who attaches the automotive slide member to the automobile or the user of the automobile. The second lubricant contains a relatively larger amount of conductive carbon than that of the first lubricant.
