Development and application of new thrust bearing for ZN series turbocharger

New thrust bearing with space surfaceoil wedge structure was developed. The New material usedfor the bearing was introduced. The Special surface coating was made for improving the bearing capacity and wearresistance, and extending the service life. The number ofcomponets for the bearing is reduced by more than 70%.Application results show that the new bearings are good inboth reliability and durability.
