speed of bearing

Hi everybody.
I understand that bearing (a normal 10 $ ball bearing for example) .. can withstand limited speed (say 3000 rpm)
if spent at further speed then we should expect heating and wearing.
my question that if I had an application with higher speed. and I used two bearings one inside the other (outer diameter of smaller bearing goes inside the inner surface of larger bearing, or even through some spacing cylinder)..
would that get a speed range of multiplication of these two bearings .. and if not .. why ??😐
