MAIN BEARINGS FOR WIND TURBINES

Looking back on more than 30 years of experience in the wind industry, Liebherr rounds off the slewing bearing portfolio for wind turbines with main bearings.

WHICH BEARING DESIGNS ARE AVAILABLE?

Depending on the type of wind turbine, triple-row roller bearings or double-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 it has zero play, therefore allowing for an optimal rolling behaviour of the bearing.

Lower tension in the adjacent construction

Double-row tapered roller bearing

Bearing with zero play and optimal rolling behaviour of the rolling elements
