That's one of my fascinations of race cars. What size bearings are normally found on NASCAR or F1 cars? 200+ MPH and heavy loaded under acceleration and braking. I'm familiar with turbines and centrifugal compressors running 14,000+ RPM on plain bearings but don't recall any equipment with ball bearings over 5,000 RPM. A Sundyne gearbox may be the exception. They had an output of 20,000 RPM+.
So what RPM is a NASCAR tire turning at 210MPH??
edit add: If our planned Spring trip happens we will be close to the Richard Childress NASCAR shop. If I can find a couple hours for a tour I'll try to find someone to ask that question of bearing size.
