REWITEC develops an innovative surface-treatment technology which is used to protect against wear and friction 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, a medium-sized company based in Lahnau, was founded in 2003 and has been part of the English chemical group Croda International Plc since 2019. REWITEC develops a innovative and patented surface-treatment technology for gears and bearings, which uses nano- and microparticles, the effectiveness of which has been proven scientifically.
Based on our 12-year experience in the wind industry and having treated more than 3000 wind turbines, we provide assistance to our customers around the world to address such issues as pitting, run through marks, downtime damage and many other risk factors that can cause wind turbine breakdowns. We offer bespoke solutions, on-site application, and pre- and post-application surface analyses.
Our technology utilises lubricants 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 so-called tribosystems 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.
