During the operation of cars and locomotives with roller bearings, oscillations in the bearing components produce slight fatigue flaws which are invisible to the human eye. These can lead to bearing failures on the road with consequent journal failures. During maintenance of these bearings in shops, inspections of components may reveal only obvious defects. For detection of fatigue flaws in the early stages of development, a reliable technology of flaw detectors is indispensable. This booklet describes the fundamental principles of magnetic flaw detection for appraisal of roller bearing components during their repair. Included is a description of basic equipment in the shops for insuring highly reliable inspection. The brochure is intended for shop and maintenance workers concerned with flaw detection. Chapters include statement of the task; basic information about principles of flaw detectors; flaw detection equipment for freight car wheelsets and inner races of the roller bearings; disassembly of roller bearing components for inspection during overhaul; and magnetic particle flaw detectors.
