... bearings are designed on the principle of rolling contact rather than sliding contact; frictional effects, although low, are not negligible, and lubrication is essential. The article lists the typical characteristics and causes of several types of failures. It describes failure by wear, failure by fretting...

... and the onset of impact fretting. In some turbines, a wire is threaded through holes in the outer ends of the blades to dampen down vibration. In this case, the frictional energy dissipated in the fretting process is the effective agent and may be considered one of the few cases where fretting is beneficial...
