.... The machine 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...

... zirconia roller. The zirconia is harder than the steel and it is capable of filing the steel, but what probably happened in this instance is that the steel adhesively transferred to the zirconia and the rubbing surfaces became essentially self-mated. It should be noted, however, that this tribosystem had...
