ELECTROCONDUCTIVE GREASE AND CONDUCTIVE GREASE-FILLED BEARING

摘要

PROBLEM TO BE SOLVED: To provide an electroconductive grease that can retain excellent electrical conductivity for a long period of time and can suppress the generation of a chemical attack phenomenon, and to provide a grease-filled bearing comprising the above electroconductive grease.;SOLUTION: This electroconductive grease comprises a carbonaceous thickening agent and an ionic fluid in a base oil, wherein the thickening agent is preferably carbon black. The conductive grease-filled bearing 3 is a roller bearing that retains a plurality of balls 3c between raceway surfaces of a coaxial inner ring 3a and a coaxial outer ring 3b, and a conductive grease 3f is sealed-in between the raceway surfaces 3a and 3b.;COPYRIGHT: (C)2007,JPO&INPIT
