REWITEC improves the service life and efficiency of gearboxes and bearings in wind turbine gearboxes through advanced surface treatment. For less downtime, lower costs and better performance - in the long term.

REWITEC at the heart of wind energy.
More efficiency. 
Less downtime.
Higher yield.

Service life and planning reliability are crucial in wind energy - expensive gearbox and bearing replacements can be significantly reduced with REWITEC.

Manufacturers and operators around the world rely on our products: Scientifically proven, REWITEC reduces wear, repairs, improves running smoothness and extends the service life of central drive components.

DuraGear® W100 extends the service life of main gearboxes until repowering - without replacement. Maintenance can be carried out flexibly and in low wind conditions.

The GR400 coating grease repairs and protects pitch, generator and main bearings as well as azimuth and pitch gears. The patented silicate technology repairs metal surfaces, reduces friction and has a preventative effect - even on new systems.

Technical managers, operators, service companies - everyone benefits. 
And many have long relied on REWITEC on a contractual basis.
The results speak for themselves:
✔ Extended service life
✔ Reduced previous damage
✔ Positive CMS data

Diversity in action.

Questions and answers 
The most important questions 
at a glance

REWITEC optimises tribologically stressed surfaces. The silicate technology repairs where friction and wear are greatest, forms a protective layer, smoothes out micro-damage and reduces friction - for less wear and more smooth running.

Our products are suitable for main gearboxes, azimuth gearboxes, main bearings, generator bearings and pitch systems - in both onshore and offshore installations.

Yes, the application not only protects stressed components, but also has a preventive effect. Young systems benefit from reduced friction and significantly less wear right from the start.

Yes, independent scientific studies, tests and expert opinions show demonstrable improvements in the friction and wear behaviour of tribological systems - even in long-term studies.

Absolutely. Many well-known maintenance and service companies already work with REWITEC and have secured the application by contract - for predictable deployment and demonstrable benefits.
