... was experiencing vibration problems and the investigators declared that the vibration problems were coming from the very large roller thrust bearing that supported the upper portion of the machine. The problem was addressed by replacing the rolling element bearing with a lubricated steel on bronze thrust bearing...

For decades, tribology researchers investigated all sorts of options to arrive at rolling-element bearings capable of operating in environments that are too harsh for conventional 52100 steel rolling element bearings. Steel bearings corrode if water from any source gets into the system...

This means that nonrotating antifriction bearings that are subject to vibration over a period of time may have fretting wear wherever a ball or roller contacts a raceway under load. If the bearings subsequently...

..., and countless places. The reason that they are so widely used is when operating at design speed, the balls will become completely separated from the raceways by the lubricant, and thus, wear becomes nil because the balls do not even touch the races. A well-designed electric motor with rolling element bearings...

When the current is broken at the contact surfaces between raceways and rolling elements, arcing or sparking occurs, producing high temperatures and localized damage. It is known that electrical discharges result from the use of an electrically...
