Addressing machine failure at the source: lubrication. To eliminate bearing failure, one must first identify the cause. On that score, most experts are already in agreement, and have been for decades: poor or inadequate lubrication is the primary cause of industrial equipment wear and failure.

Ask customer for assessment of what happened leading up to bearing failure. Bearing Inspection - in operation Notify operator of machine you are in the area conducting the inspection on the bearing. Review XOM JSA with Site personnel. Use IR gun, thermography camera or temperature indicators to obtain bearing and surrounding component temperatures.
The proposed technique is validated using the vibration output of seeded fault steel bearings on a bearing test rig. The result is an effective approach validated to diagnose all four bearing fault types: inner race, outer race, ball, and cage.

I f you ask anybody who's been around maintenance why precision lubrication is important, nine times out of 10 he or she will answer "to prevent failures." While this basic statement cannot be argued, let's stop to consider the actual meaning of a failure. The two most common types of failure are catastrophic and functional.
Failure to Prevent Lubricant Contamination Lubricant contamination is a leading cause of bearing failure. Dirt particles, other contaminants and the application of incompatible grease are all factors that increase equipment failures. The use of two incompatible lubricants will lead to deterioration in
I would not agree that over greasing it is the main (emphasize “main”) cause of failure nor would most bearing manufacturers. I believe most bearing manufacturers feel that improper installation procedures are a major reason for bearing failure.
The debris that enters the oil begins abrasion damage. Once the bearing surface becomes incapable of supporting an oil film, the bearing will wipe. The bearing may recover an oil film and continue to operate, and pitting will begin again. This process may occur several times before the inevitable catastrophic bearing failure.

What Causes Bearing Failures? The more we learn about bearings and why they fail, the better we can protect equipment from unnecessary repair and...
Bearing failure due to lubrication is a very common occurrence. About 50% of bearing failure is related to lubrication. Below is a section of an article from www.machinerylubrication.com that details eight failure mechanisms. (Full article can be read here.). When in doubt, it does not hurt to ask when lubrication comes into play.
5 Ways to Prevent Bearing Failures As seen in Machinery Lubrication (4/2012) Steven Katz, Emerson Bearing Tags: bearing lubrication, greases, contamination control The accurate diagnosis of a bearing failure is imperative to prevent repeat
Knowing how water attacks and causes damage helps in setting important dryness targets and also aids failure investigations post mortem. Further, when water contamination is unavoidable, understanding these water-induced failure modes can be valuable in the optimum selection of lubricants, bearings and seals for defensive purposes.
When it comes to eliminating failure modes and improving equipment reliability, developing a sound lubrication programme might be the first place every company should begin. For whatever reason, companies around the world have always ignored the fundamental elements of a good lubrication programme.

In fact, some studies have found that improper lubrication causes up to half of all bearing failures. Even when poor lubrication practices do not necessarily result in equipment failure, it may lead to inefficient maintenance processes.
…and 5 ways to avoid it! Mae West famously said, “Too much of a good thing can be wonderful.” Although we don’t know just what she was referring to, chances are pretty good it wasn’t lubrication of bearings, because in this case, too much is just as bad as not enough.
In conclusion, regardless of whether you have a lubricant- or contaminant-induced failure mechanism, the result will either lead to lubrication failure modes or contribute directly to mechanical failure modes of the bearing. When multiple failure mechanisms are combined, there is greater potential for a lubricant failure.
The Hidden Dangers of Lubricant Starvation For those who strive for lubrication-enabled reliability (LER), more than 95 percent of the opportunity comes from paying close attention to the "Big Four." ... However, more moderate partial starvation is what tends to go unnoticed until failure. Then, other suspect causes (the bearing, lubricant ...
