Product Description

T- MAN Turbocharger / T- NA Series Turbo Rotor Assembly For Marine Engine Turbocharger Spares

T- MAN / T- NA series turbocharger design features:

T- NA series turbocharger rotor assembly (also called rotor complete) belongs to a part of T- MAN / T- NA turbochargers, which were developed comparatively simply with a cast axial turbine, which is suitable for heavy fuel oil engines, marine diesel oil engines, biofuel and gas operation enginess. 

  • T- MAN / T- NA turbochargers adopts inboard plain bearing, uncooled casings and lubricated by the engine's lube oil system.
  • For engine power output range from 1,650 to 24,500 kW per turbocharger;
  • Axial flow turbine inboard plain bearing design;
  • Lubricated by the engines lube oil system;
  • Suitable for a wide variety of fuels, heavy fuel, diesel oil, biofuel and gas operation;
  • Simple and durable design;
  • Easy maintenance or overhaul;
  • Long service life;
  • widely used in marine, power and industrial applications.


T- NA series turbocharger is widely used in Marine engine, Power engine and Industrial engine.

T- NA series turbocharger includes:

The description of turbocharger rotor assembly / rotor complete:

  • The turbocharger rotor assembly / rotor complete consists of compressor impeller, blade shaf/turbine shaft/rotor shaft and partition wall complete.

  • The compressor impeller is of aluminium alloy or the more expensive titanium. Manufactured from a single casting it is located on the rotor shaft by splines. Aluminium impellers have a limited life, due to creep, which is dictated by the final air temperature.

  • The turbocharger rotor shaft is equipped with components such as a compressor and a turbine impeller, and has a complicated structure and a large weight. If the ship is parked for a long time, the turbocharger rotor will be bent and deformed due to the long-term non-operating self-weight.

  • After a period of operation, the turbocharger is deformed or broken due to severe carbon deposits on the turbine blades; the compressor impeller, blade deformation or damage will change the rotor mass distribution, changing the original center of gravity of the rotor and destroying the original dynamic balance accuracy of the rotor produces severe vibration and the work is not stable.

    So doing the rotor dynamic balance test is very important when the replacement parts is about to dispatch to the end user.
