thyssenkrupp rothe erde as a professional companion in the exchange of bearings and repair of used bearings.

Bearing exchange and repair

When the wear limits are reached, a bearing replacement is mandatory. We accompany you throughout the entire process: From repair and replacement to the re-commissioning of your slewing bearing.

Our service and consulting services

Exchanging bearings always requires downtimes and therefore causes high costs. We apply our wealth of experience and make sure that you can put your plant back into operation as quickly as possible.

We support you with:

  • Creation of schedules
  • Loosening of bolts or – if necessary – blasting of nuts
  • Removal of the old bearing
  • Measurement of the bearing connection surfaces
  • Positioning and bolting of the new bearing
  • Recommissioning


We check the dismantled bearing either directly at your site or at our factory. In doing so, we identify the causes of the failure and point out repair options. You can use the knowledge we gain to optimize your bearing design. This applies not only to day-to-day operations: Even after accidental damage, we check your bearing for possible further use.

We support you with:

  • Failure detection
  • Damage assessment
  • Repair of bearings
  • Concept optimizations

General overhaul

Various repair options are available depending on the inspection results. We coordinate the individual steps of the general overhaul with you and also take into account the economic aspects of the repair measures.

We assist you with:

  • Mechanical reworking of the raceway system
  • Mechanical reworking of all external contours
  • Reworking of the gearing
  • Adaptation of new bearing rings
  • Exchange of anti-friction bearing bodies, cages and seals
  • Recertification


As the technical development of slewing bearings is constantly evolving, there are opportunities for optimizing bearings that have already been produced. We offer you an upgrade to the most modern bearing concepts. To this end, we check and evaluate the technical basis of your bearing and show you possible changes.

We support you with:

  • Technical testing
  • Evaluation of optimization potential
  • Upgrade to state-of-the-art bearing concepts
