요약 Electrically insulated bearings coated with Polyphenylene sulfide resin (PPS) are currently used in traction motors on railway rolling stock to prevent electric corrosion. However, the internal temperature rise in the PPS insulated bearings is higher than in ordinary bearings because the thermal conductivity of the PPS is low and the PPS layer also acts as a heat insulator. A change of interf..
