Review of WindEnergy Hamburg 2024

Innovative Solutions Highlight the World's Leading Trade Fair for the Wind Industry

WindEnergy Hamburg 2024 concluded after four dynamic days filled with engaging discussions. During this period, approximately 40,000 visitors explored the exhibition halls. The spotlight was on the increasing power density of wind turbines, a decisive factor for the planned expansion targets for renewable energies.

As a market leader and strategic development partner, Schaeffler actively contributed to these conversations. With over 40 years of experience, we not only provide optimal bearing solutions for wind turbines, but also drive the advancement of multi-megawatt turbines through our comprehensive system expertise.

Let the solutions showcased at WindEnergy Hamburg inspire you.

Closed Loop Engineering
Cost-effective wind turbines depend on reliable components that enable ever-increasing power density. As engineering partner for turbine and gearbox manufacturers, Schaeffler leverages comprehensive system knowledge to advance the development of wind turbines. Using state-of-the-art simulation, real-world testing, and field-based measurements, we do more than improve our products – we optimize the entire drivetrain.
World’s most powerful main bearing test facility
To ensure the reliability of our wind turbine bearings, we subject them to comprehensive testing. That’s why we are currently engaged in a significant expansion of our bearing testing capacity. In cooperation with LORC and R&D Test Systems, the world’s most powerful test bench for wind turbine main bearings is being built in Lindø, Denmark. Schaeffler played a major part in defining the specifications. The new test rig enables us to test the wind turbine bearings under realistic conditions - far beyond conventional standards.
Hydrodynamic plain bearings in series production
Modern, high-performance wind turbine gearboxes operate with as many planets as possible in order to be able to handle the constantly increasing torques. Extremely robust hydrodynamic plain bearings from Schaeffler enable this power density to be achieved in the smallest possible installation space. We are capable of not only calculating and simulating traditional rolling bearings but also the new hydrodynamic plain bearings for gearboxes, which are now being produced in series.

Revolutionary repair solution
Our split asymmetric spherical roller bearing makes it possible for the first time to replace the rotor bearing directly in the nacelle. Disassembly of the rotor star and the entire drive train is no longer necessary. This means that replacement costs can be more than halved and older turbines can continue to operate economically.
Energy revolution with green hydrogen
For energy-intensive industries, green hydrogen is a beacon of hope on the path to a climate-neutral future. Electrolyzers equipped Schaeffler's innovative stacks are at the heart of hydrogen production. Modular systems enable decentralized hydrogen production on an industrial scale. The Hydron Powerstack K series covers a range of applications from 1kW to 1MW and is produced to the highest quality standards at Schaeffler production sites in Europe.
