Longer life and higher efficiency for your wind turbines

REWITEC has developed an innovative surface-treatment technology which is used to protect and repair gearboxes and bearings in wind turbines in situ and increase their efficiency.


Our innovative REWITEC technology protects and repairs the surfaces of gears and bearings in wind turbines.

REWITEC GmbH, which was founded in 2003 is a medium-sized company based in Lahnau, Hessia. REWITEC has developed a patented and innovative surface-treatment technology for the protection and repair of gears and bearings, which uses silicate nano- and microparticles via a lubricant carrier. The effectiveness of the treatment has been proven scientifically.

Based on our 15-year experience in the wind industry and having treated several thousand wind turbines, we provide assistance to our customers around the world to address such issues as surface pittings, spalling, WECs and other damages, and many other risk factors that could result in wind turbine outages. We offer our clients bespoke solutions, on-site application, and pre- and post-application surface analyses.

Our technology
Our technology utilises lubricants and bearing grease as media to form a self-repairing silicate layer of particles on the metal surfaces of gears and bearings. This ensures greater reliability, improved energy efficiency and a long service life in drive system components by significantly reducing surface roughness, friction, and temperature, which results, among other things, in a more even load distribution on the tooth flanks and in the bearing components. The technology can be used in both oil and grease lubricated systems.

- Repairs damaged gear and bearing surfaces
- Significantly extends the service life of drive components
- Reduces wear and increases operational smoothness
- Scientifically proven friction reduction and efficiency increase
- Suitable for use in old and new wind turbines
- Significant reduction in maintenance costs
