Main bearings for wind turbines - Liebherr

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.

bearings, driveshafts, and precision equipments - Products by Market:Wind Turbine…

Tapered roller bearings are designed so the inner and outer ring raceway and the apex of the tapered rollers intersect at one point on the bearing centerline. For this reason, the rollers are pushed against the inner ring rib and roll guided by the rib, receiving the loads from the inner ring raceway surface and the outer ring raceway surface as a coined load on the raceway surface.

The world of bearings | SKF Wind News

31/8/2018· Spherical roller bearings. Spherical roller bearings typically have two rows of rollers that run in two raceways. This design enables them to withstand both high radial and axial loads, while reducing friction and consequent heat. They are most commonly used in the main shaft of wind turbines but were often previously deployed in gearboxes. 2.
