The biggest price paid on ball bearing turbos is continuous motion and pressure.
In the racing world with leaded fuels ceramic bearings will get contaminated with the lead in the fuel and these deposits also cause premature failures.
This is mostly due to the additional time spent to perfect a quality ceramic ball.
To illustrate this practically a small experiment was carried out to neutralize the effects of grease and seals.
