The most common causes of failure include:
Condition Monitoring is the process of monitoring parameters of condition in a machine, such that a certain data set is indicative of a developing imminent breakdown.
A form of electrical pitting. The pit marks caused by electrical fluting usually appear as closely spaced lines running parallel to the bearing shaft.
A type of infrared imaging science that detects radiation in the infrared range of the electromagnetic spectrum and produces images of that radiation, called thermograms. The amount of radiation emitted by an object increases with temperature, therefore thermography allows one to see variations in temperature.
The use of a laser to align machinery with precision. The resulting high degree of accuracy is required for the proper operation of many industrial applications to ensure product quality.
