Vibration was detected by a piezoelectric accelerometer mounted on the bearing housing and was recorded by a magnetic tape recorder which was controlled by a microcomputer. In total, twenty-seven bearings were tested, and flaking failures were generated in twenty-six of them; nineteen on the outer races, five on the inner races and two on the balls. In most cases, flakings grew gradually with obvious changes of vibration, thus enabling the early detection of the defects in the bearings. However, in some bearings, flakings were generated very rapidly, limiting the usefulness of the condition monitoring.", "subitem_description_type": "Other"}]}, "item_3_description_32":
