ELECTRIC CORROSION PREVENTION ROLLING BEARING AND MANUFACTURING METHOD OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an electric corrosion prevention rolling bearing which uses a ceramic material having heat conductivity higher than alumina for an insulation coat and thereby achieves excellent electric insulation performance and heat radiation performance.SOLUTION: An electric corrosion prevention rolling bearing includes an insulation coat in at least one of an inner race and an outer race. In the electric corrosion prevention rolling bearing, the insulation coat is made of aluminum nitride.
