Document Type and Number:
WIPO Patent Application WO/2024/014015
Kind Code:
A1
Abstract:
[Problem] The purpose of the present invention is to provide an anti-electrolytic corrosion rolling bearing configured such that the occurrence of gaps between the inner ring or outer ring and the insulation coating caused by shrinkage during insert molding can be suitably suppressed to ensure a satisfactory electric corrosion preventive effect. [Solution] An anti-electrolytic corrosion rolling bearing according to the present invention is typically configured such that a resin insulation coating is formed on the surface of an inner or outer ring by insert molding. The anti-electrolytic corrosion rolling bearing is characterized in that the inner circumferential surface of the inner ring or the outer circumferential surface of the outer ring has grooves formed therein; the grooves are on both sides of the bearing center, extending in the circumferential direction; and the inner walls on the center side of the grooves are inclined toward the center in the depth direction.
