PROBLEM TO BE SOLVED: To provide a rolling bearing improved for a decrease in volume resistivity without causing a decrease in strength of a contact rubber seal, thus producing a stable effect of electric conduction. SOLUTION: The conductive contact rubber seal 5 molded with carbon black and conductive fibers 12 mixed therein has its outside diameter 7 fitted around an outer ring 1 and has its inside diameter 8 disposed to be slidable against an inner ring 2 to thereby reduce its volume resistivity and enhance its conductivity. |
