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

Keep the nose in the wind: Azimuth (yaw) drives optimally align your nacelle with the prevailing wind direction. With yaw drives from Liebherr, you are choosing high-quality, durable and low-maintenance components that extend the service life of your wind turbine.

Product advantages at a glance:

• compact design, high power density
• outstanding product quality
• on request: Customisation to customer requirements
• Optionally with pre-assembled electric motors

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.

Product advantages at a glance:

• robust and long-lasting design
• maximum reliability thanks to precise manufacturing
• safe components through quality testing according to strict industry requirements
• low-wear thanks to slip-free hardened raceways

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

Bearings for blade adjustment are subject to special loads like partial standstill, small rotations, and changing loads.

To increase bearing lifetime and optimize the prevention of idle marks and false brinelling marks, Liebherr co-developed a specialized grease for pitch and yaw bearings:

Liebherr Duro Wind PBG is a performance leader in key areas – especially in the low temperature range:

• Wear protection
• Low temperature properties
• Vapour phase corrosion protection
• False brinelling (Riffel test)

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.

Liebherr Corrosion Protection

Extend the life of your bearings and effectively prevent corrosion and cracking against boreholes among other things.

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