Title:
INSULATED ROLLING BEARING
Document Type and Number:
WIPO Patent Application WO/2024/071187
Kind Code:
A1
Abstract:
Provided is an insulated rolling bearing having an insulating coating on the outer peripheral surface of an outer ring or another such location, the insulated rolling bearing being exceptional in terms of properties for preventing electrolytic corrosion. This insulating rolling bearing 1 comprises an inner ring 2, an outer ring 3, raceway surfaces that are formed on the outer peripheral surface of the inner ring 2 and the inner peripheral surface of the outer ring 3, and a plurality of balls 4 that are interposed between the raceway surfaces, the outer peripheral surface 3a of the outer ring 3 having a resin coating 6 (insulating coating), and the resin coating 6 in the insulated rolling bearing 1 being composed of a resin composition having an insulation resistance value of 2000 MΩ or greater and a capacitance of10 nF or lower, the resin composition containing a polyphenylene sulfide resin, glass fibers, an inorganic filler having a thermal conductance of 10 W/m·K or greater, and a thermoplastic elastomer.
