T- TPL Series Turbocharger Bearing Thrust Bearing In Engine Lube Oil System
T- TPL series turbocharger design features:
T- TPL series turbocharger includes T- TPL-A series (T- TPL65, T- TPL69, T- TPL73 and T- TPL77) and T- TPL-B series (T- TPL73-B, T- TPL77-B, T- TPL80-B, T- TPL85-B, T- TPL91-B).
- The T- TPL-A series turbocharger is for large medium-speed diesel and gas engines, with a power output range from2,500kW to 12,500kW.
- Turbine: The T- TPL-A turbocharger is axial turbine for high efficiencies and high volume flow rates.
- Compressor: The T- TPL-A comressors ensure the high volume flow rates which allow optimized matching to different engine applications. Its single-piece, splitter-bladed aluminum alloy wheels with backswept blades ensure high efficiencies and wide compressor maps. its pressure ratio is from 4.2 up to 5.0 based on different design.
- Bearing: The T- TPL-A bearing assembly lubricated directly by the engine lube oil system, plain bearings can run up to 36,000 hours before being overhauled.
- T- TPL-B series turbocharger is designed primarily for large two-stroke marine diesel engines. These turbochargers are simple, rugged and compact to keep your running cost low. Five frames cover an engine output range of 3,000kW to 28,000kW.
- Turbine: The T- TPL-B turbocharger is axial turbine for very high efficiencies and high volume flow rates by the 2-stroke diesel engine market.
- Compressor: The T- TPL-B comressors ensure the high volume flow rates which allow optimized matching to different engine applications. Its single-piece, splitter-bladed aluminum alloy wheels with backswept blades ensure a wide compressor map and peak efficiencies of more than 86%. its pressure ratio is up to 4.5.
- Bearing: The T- TPL-B bearing assembly lubricated directly by the engine lube oil system, plain bearings are designed to run up to 36,000 hours before being exchanged. The radial bearing bushes are fixed with screws and centered in a squeeze oil film damper.

Description of turbo bearing and turbocharger thrust bearing:
T- TPL series Turbo Bearing / Turbocharger 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 superchargers 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)
