Authorised Workshop for SLF Hybrid Bearings

Bearings are a critical component of the Turbocharger which effects its durability and reliability. For this high loaded application, TurboSpares supplies complete adjusted bearing assemblies, properly packed in tins for long time storage and with a unique ID-Number.

SLF super precision ball- and roller bearings

Turbocharger bearings can be split into two main types: hydrodynamic journal bearing systems and ball-/ roller bearing systems. TurboSpares has a reliable improved option for ball- and roller bearings, especially designed for the VTR-4 series Turbochargers. For these complete bearing units we use the German designed and made, SLF super precision ball- and roller bearings, with P4 accuracy.

More advanced steel and ceramic rolling elements

The Turbocharger demands a high load bearing capacity and at the same time high rotating speeds. In the high loaded Compressor End (CE) bearing assembly we use the special designed SLF Hybrid bearings. The rolling elements are made of ceramic Si3N4, the rings from X30 (known from aerospace applications) and the cage is made of PEEK material. 

The Turbine End (TE) bearings are assembled with standard steel rollers, but on special request we can assembly these bearings with ceramic rollers as well. The advantage of using these ceramic bearings can be found in a more reliable performance, less false brinelling, less wear and heat generation.

Cooperation between TurboSpares and SLF

The assembly of a complete bearing unit demands a high level of specialism and accuracy. In our temperature controlled state of the art bearing room, all bearing components are properly stored and carefully measured. The combination of TurboSpares’ technical expertise with the innovative and special designed SLF Hybrid bearings, makes our bearing unit one of the most reliable.

This improved and innovative bearing concept is applicable to all kind of applications in Marine, Power Generation and Industry. In case of special Engine applications and circumstances, do not hesitate to contact our technical department for advice.
