T- ABB / T- A170 Turbo Bearings, Spacer Sleeve, Turbocharger Thrust Bearing In Low Speed Marine Turbocharger Engines

T- ABB / T- A100-L series marine turbocharger's design features:

T- A170 type turbo bearings, space sleeve, turbocharger thrust bearing belongs to the parts of T- ABB / T- A100-L series exhaust gast turbocharger with the features as below:

• High efficiency;
• High pressure ratios: the A100-L is capable of delivering pressure ratios up to 5.0 combined with a high specific air volume flow.
• Low noise: the air outlet silencer is integrated in the compressor casing for very effective noise reduction;
• Step up performance with High Pressure Tuning (HPT): 1. Higher peak firing pressures at low and part load achieved by an increase in the engine’s scavenging air pressure; 2. No excessive firing at full load thanks to an electronic management system that varies compression ratio in each cylinder by controlling the timing of the exhaust valves; 3. Lower fuel consumption of up to 5 g /kWh; 4. HPT saves money for engine builders, ship owners and operators:
• Good design and inherent simplicity of the A100-L series turbocharger make the easy maintenance and overhaul possble.

Description of turbo bearings, spacer sleeve, turbocharger thrust bearing:

​Turbo bearings play an important role in turbochargers. They not only ensure safe and reliable high-speed rotation of the rotor, but also ensure that the rotor is fixed in the correct position. Therefore, the reliability of the bearing is extremely relevant to the normal operation of the supercharger and the diesel engine. Turbocharger bearings are divided into rolling and sliding, marine turbochargers mostly use rolling bearings, in addition to thrust bearings.

A thrust bearing is a particular type of rotary bearing. Like other rotary bearings they permit rotation between parts, but they are designed to support a high axial load while doing this (parallel to the shaft). Different kinds of thrust ball bearings are used to support different amounts of axial load.(From Wikipedia)

Turbocharger bearings work under high temperature, high speed and light load conditions to ensure reliable operation of the bearings under working conditions. In addition to ensuring that the structural design, materials and manufacturing of the bearings to meet the requirements, good maintenance management is also critical important.
