Heavy Duty Fuel Oil 311mm Turbo Bearing Housing

Turbo Bearing Housing features:

T- marine turbocharger casing type T- AT14 water-cooled bearing casing is belonging to T- exhaust gas turbocharger and which has the following characters:

• T-/ T- AT14 turbochargers is high pressure ratio turbocharger for use with 500 kW class marine engines.

• T-AT14 turbocharger compressor is capable of achieving a maximum pressure ratio of 5.0.

• T-AT14 turbochargers applied in diesel engine and its output can cover approx. 320-750 kW.

• T-AT14 turbocharger has enough reliability and durability even under the heavy duty fuel oil application.

Turbo Bearing Housing include:

Turbo Bearing Housing Applications:

Automotive, heavy truck, construction, marine and industrial engine.

T- / T- AT14 turbocharger construction and outer dimensions:

The above T- AT14 Turbocharger's cross-sectional drawing shows that the T-AT14 turbocharger is consisted of the turbine and compressor, and the thrust bearing and two journal bearings which make the axial and radial forces respectively becoming possible. From static section view, T-T- T- AT14 turbocharger consists of the compressor housing, bearing housing and turbine housing.

Distance between two journal bearings is approx. 60mm;

The rotor length is about 300mm;

The inclusion of turbocharger casing:

The turbocharger includes turbine part, bearing part and compressor part, so the turbine housing, bearing casing and compressor housings cover and protect all the important parts safely in the turbocharger to ensure a premium perforce of the engine.

The turbine casing, bearing casing and compressor housing are made by cast iron. Some casings are water cooled which complicates the casting. Water cooled casings are necessary for turbochargers with ball and roller bearings with their own integral LO supply (to keep the LO cool). Modern turbochargers with externally lubricated journal bearings have uncooled casings. This leads to greater overall efficiency as less heat energy is rejected to cooling water and is available for the exhaust gas boiler.
