Nodes bearing has NSK Ceramic bearings in stock. To prevent electric pitting, NSK developed ceramic coating insulated bearings and PPS-resin coating insulated bearings. Relationship between temperature and insulation resistance of ceramic-insulated bearings was assessed. As a result, no deterioration of insulation resistance up to 110° C was observed.
