REWITEC has developed an innovative surface-treatment technology which is used to protect against wear and tear and to repair damaged surfaces in wind turbine gearboxes and bearings.
Our innovative REWITEC technology protects and repairs the surfaces of gears and bearings in wind turbines.
REWITEC GmbH, which was founded in 2003 and has been part of the US Cargill Group since July 2022, is a medium-sized company based in Lahnau. REWITEC has developed a patented and innovative surface-treatment technology for the protection and repair of gears and bearings, which uses nano- and microparticles, the effectiveness of which 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 pitting, run-outs, downtime damage, 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 silicon 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.
