Almost all double ball bearing systems that have been designed by various turbocharger manufactures have failed to meet necessary durability requirements. Garrett gt2876r aka gt25 40r ball bearing turbo dual ball bearing gt25 40 r turbo assembly with specified ar. 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. When it comes to turbochargers in aircraft the simple solution is still the best solution.

Axial movement float gap clearance is adjusted to 0 005mm 5μm 0 01mm turbocharger longevity increases greatly. Hydrodynamic bearings are proven to be better for aircraft engines. The ceramic bearings can actually become contaminated with lead deposits from avgas which can also lead to premature failure.
