Our wind energy solutions - We empower industries to break new ground and master the shift into a sustainable future

Rothe Erde's goal is to decisively advance the generation of energy from environmentally friendly and renewable sources. We support the growth of the industry by supplying key components for wind turbines. Our wind bearings can be manufactured in the following designs:

single-row designs,
multi-row designs,
clamped internals,
bolted internals,
case-hardened raceways or
slip-free induction-hardened raceways.

We know the requirements of the wind industry and our customers inside out, and are able to offer you the solutions of tomorrow with our engineering expertise:

New standards for equipping wind turbines

Our products enhance the efficiency of wind turbines globally, making them a competitive alternative to fossil fuels. Rothe Erde is constantly working to ensure that our bearing solutions for wind turbines, and at the same time our customers, contribute to a more environmentally friendly future.

To achieve our goals holistically, we combine technical excellence with the possibilities of the digital world. As a result, we develop advanced solutions specifically designed for the wind industry and individually tailored to our customers. We consistently remain at the forefront of innovation.
