ABB / TPL-B series turbocharger design features:

TPL series turbocharger seals thrust bearing belongs to one part of ABB / TPL series turbocharger, and TPL series is devided to TPL-A Series and TPL-B series. Hereblow are the design features for TPL-B Series turbocharger as per reference:

• it 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 TPL-B turbocharger is axial turbine for very high efficiencies and high volume flow rates by the 2-stroke diesel engine market.
• Compressor: The 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 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.
• Casing: The  TPL-B casings are optimized for 2-stroke engines. Features include integrated washing device, temperature and pressure measurement. The TPL-B casing is insulated to make the turbocharger noise level and casing surface temperature as low as possible.
• Emergency lube oil systme: it ensures safe running of the TPL85-B and TPL91-B turbocharger rotor.

Definition of thrust bearing:

ABB TPL series turbocharger 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)
