to prevent electric pitting, developed . relationship between temperature and insulation resistance of ceramic coating insulated bearings was assessed. as a result, no deterioration of insulation resistance up to 110° c was observed.
roller bearings are used in all for electric engines and electric cars. usually, cylindrical roller bearings are utilized due to their high speed and heavy-load capabilities, as well as their ease of assembly and disassembly. in the case of small motors, deep groove ball bearings may also be used.
