The ball bearings used in most electric motors are pre-greased, shielded ball bearings. normal motor bearing operating temperatures range from 140 to 160 f. as in all bearing applications, this measurement should be taken at the bearing outer ring. if the outer ring is inaccessible, take the measurement at the housing and add 15 to 20 f.
