 · Failure Analysis of Arcing and Contact Fatigue of Ball Bearings Summary: The four seized bearings submitted for metallurgical analysis were determined to have suffered deterioration of their grease to the point that it was inhibiting motion rather than enabling. The grease had turned to a thick (viscous) black sludge that was full of particulate.

Failure Analysis / Investigation

Failure Analysis / Investigation

Failure analysis is a process of collecting and analysing facts or data to determine a probable root cause of a failure. This involves collecting data about operating conditions, visual examination of the failed product or component, fractography, nondestructive testing, evaluation of mechanical and chemical properties, metallography ...

Rolling element bearing components and failing frequencies ...

Rolling element bearings consist of several clearly differentiated components: inner race, balls or rollers, cage and outer race. The deterioration of each of these elements will generate one or more characteristic failing frequencies in the frequency spectra that will allow us a quick and easy identifiion.

Failure Rate Estimates for Mechanical Components

The average failure rate for a population of these bearings is estimated to be approximately 20 FPMH, as depicted by the green line shown in the lefthand figure below. Conversely, if the bearing is replaced every 2 years, the failure rate will vary between 0 at "time zero" to 19 FPMH at the two year point, with the average failure rate ...
