But are ball bearings much more common than other types? And what about bearings with moving parts compared to fluid/magnetic bearings, or plain bearings?

What would you charge for eight bearings of comparable quality?

Being a Swedish ME student, SKF is mentioned quite a lot, and as I understand it they're a relatively large ball bearing supplier. What's their reputation like out in the real life? And what's the reputation like of other big manufacturers? Are there any you would go to for bearings with a specific use in mind?

What's the biggest news in bearing science and development at the moment?
