Bearings fail.
Porsche Land had a Link to their Facebook Fanpage above. So they sell an own IMS solution:

Interesting is what kind of bearing they use. I did some research in the last days - Nachi, SKF, and a lot of other manufacturers on 6204 bearings. Well, if someone does that he will note that there are a lot of differences between roller bearing and ball bearings concerning max rpm capacity.
