COAL-FIRED POWER plants use gearboxes located on the top of each coal pulverizer to drive the rotating classifier. Rotating classifiers ensure that the coal is of the appropriate size for proper ...

Machine tool spindles serve as the backbone to numerous manufacturing sectors, enabling creation of precision-engineered components with exceptional accuracy. However, there is a persistent problem at ...

What do clocks, skateboards, and industrial machinery have in common? They all rely on bearings to maintain their smooth rotational movements. However, to achieve reliability, they must be maintained ...

Hydropower is among the most mature and reliable renewable energy technologies, but its dependability rests on thousands of tonnes of rotating equipment humming quietly for decades. Generators are at ...

The difference between good and bad in the wheel bearing world is a very fine line — about the width of a couple of human hairs, to be imprecise. That's not much of a margin considering the potential ...

A minor coal train derailment in Virginia in early July prompted Norfolk Southern to rethink the way it responds to problems with overheating bearings, but it’s not clear why the railroad didn’t make ...
