Turbochargersturbine is used for most of the medium and large size engines suitable for rail traction Consider the basic requirements of the gas expander for a turbocharger. Turbines may be radial, axial or mixed flow type, the frrst mentioned being ideal for self-contained lubrication systems when using rolling-contact bearings

Friction Characterization of Turbocharger Bearings - KTHMar 7, 2013 — The axial force acting on the turbocharger thrust bearing has a great influence on the oil film diesel engines while the usage on gasoline engines is increasing. maintain a long service life, improve operational reliability and keep Roller contact bearings are very advantages regarding frictional losses

ABB Turbocharging VTR4 have major benefits for engine- builders and end-users alike. The rotor runs in spring-mounted, rolling-contact bearings, which can be easily accessed from Turbocharger bearing lubrication system - DieselShipApr 7, 2016 — – The ball and roller bearings are mounted in resilient mountings incorporating spring damping to prevent damage due to vibration. These bearings have their own integral oil pumps and oil supply, and have a limited life (8000 hrs)
