Original spare parts from KBB

If you provide us with the data on your exhaust-gas turbocharger’s nameplate (type, spec. and serial), we can make you an individual offer according to your wishes or service case.

We are proud of our patented manufacturing methods to produce turbine nozzle rings that are either uncoated or especially coated for operation with heavy fuel oil. They are one of the most important parts of our exhaust-gas turbochargers. Our original KBB turbine nozzle rings guarantee the best performance.

We pay great attention to making our plain bearings as precise as possible. They are crucial for the smooth running of the rotor and thus for the quality and efficiency of our exhaust-gas turbochargers. Regular replacement of the bearings can reduce your costs significantly in the long run.

The perfect rotor in perfect condition is synonymous with performance, efficiency & cost reduction. An exhaust-gas turbocharger can only achieve the performance you expect with the right rotor in a perfect condition. At the same time, a perfectly matched and precisely manufactured rotor also guarantees the highest possible safety and efficiency. And the best thing at all – just leave it up to us.

We take care of your rotor, be it axial or radial. Our service stations and KBB staff are ideally trained to carry out all necessary inspections and maintenance work on your rotor.

Cut costs with clever packages. Our spare parts strategy aims to reduce your costs. We have the right sets of spare parts for every servicing task and we sell them as a package. This means that you have all of the spare parts you need on site at all times and can rest assured that the next inspection will go off without a hitch.

Simply send us the details from your turbocharger's nameplate and we will help you select the correct parts.

A cartridge contains all of the parts of your turbocharger that are subject to mechanical stress. Regular inspections and/or maintenance that are carried out with a meticulous attention to detail are thus essential for a fully functioning exhaust-gas turbocharger.

A quick replacement of the complete cartridge may be expedient to guarantee extremely short engine downtimes during our servicing work. We can also supply spare cartridges at short notice across the globe.

Feel free to contact us at KBB directly or get in touch with your local KBB service partnerto schedule all of your inspections and maintenance work.

Resource efficiency through remanufacturing

KBB is well aware of its responsibility towards the environment, which is why we encourage the reuse of core components.

Remanufacturing also allows updates to meet current design standards. The components are reworked according to original or current specifications, as required.

Dismantling and cleaning

We make an initial evaluation of the turbocharger after its delivery. To this end, it is dismantled and the individual parts are specially cleaned so as to allow an exact assessment.


All of the parts are inspected, measured and tested very carefully. The same standards apply here as for new parts in order to meet the high requirements of the components in operation.

Processing & assembly

Any component that does not meet our strict requirements or is not up to the latest technical standard will be replaced by a new part.

Final check

Every turbocharger is subjected to a hot gas test run after assembly in our test centre to ensure its quality. This allows us to guarantee its full performance and perfect function.

Coating & shipping

Finally, all of our turbochargers are coated and preserved, the same as in our series production. This protects them against environmental influences and allows a fast final assembly on the customers‘ premises.

Whether repairs or new parts:

All of our parts undergo the same process in compliance with the KBB quality standards and specifications. We grant a 1-year warranty on all parts and service work.

KBB breathes new life into second-hand components.

We believe it’s worth the effort: because our remanufacturing programme spares resources and thus reduces the load on the environment, entirely in accordance with our corporate policy.
