    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 ??😐
