Components for wind energy

The asymmetrical raceway of Liebherr yaw bearings means they are perfectly designed for swivelling heavy nacelle loads.

Increase the service life of your systems with high-quality and durable yaw bearings from Liebherr.

Product advantages at a glance:

• long service life thanks to optimised bearing design
• high-quality double seals prevent leaks
• extensive service and consulting

Main bearings are the core of your wind turbine. Enjoy ultimate processing quality and absolute reliability.

Depending on the type of wind turbine, triple-row roller bearings, double-row tapered roller bearings or single-row tapered roller bearings are used as main bearings. While the roller bearing leads to lower stresses in the adjacent construction, the tapered roller bearing is particularly attractive because there is no play, which helps keep functioning of the rolling element optimal. We would be happy to help you the best component.

Liebherr FAT tests: Monitor the condition of your bearings to prevent damage and ensure maximum plant availability.

Liebherr FAT tests:

• Predictive wear and tear measurement prevent
• bearing damage and production downtime
• Rapid, independent analysis and evaluation of your samples
• Efficient planning of repairs, oil changes or replacements

Avoid cage damage and edge breakage due to high loads and operational errors.

Take advantage of:

• optimised micro-geometry of your bearing’s raceway form
• long service life of your cages through accurate roundness, hardened materials and state-of-the-art manufacturing methods
• 30% more load-bearing capacity with the same installation space with our ROD blade bearings

Plant protection through application-optimised bearing designs

Liebherr has been further developing its Finite Element Analysis (FEM) of bearings for years. In addition to the bearing, the blade and hub geometry are included in the calculations.

Prevent gear damage efficiently: The innovative lubricating pinion from Liebherr reliably prevents wear and helps to avoid bearing damage.
