Hybrid ceramic ball bearing turbocharger, including the compressor shell, turbine shell, bearing body, seal kits, turbine rotor, hybrid bearings, hybrid bearings as described in hybrid ceramic ball bearings. Hybrid ceramic ball bearings bearings mounted on the mixing between the inner and outer ring hybrid bearings to replace the ordinary ball-bearing steel ball, played reduce friction, lower temperature and lower pairs of bearing lubrication conditions, demand for greater elastic modulus to improve the startup performance of bearings and so on. The invention uses hybrid ceramic ball bearings improve the speed, thereby increasing turbocharger speed performance, service life and reliability, while bearing weight. Compared with the existing oil film bearings, hybrid ceramic ball bearings can support axial loads, so cancel thrust bearing, reducing parts, simplified turbocharger bearing system architecture.
