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.
Steels for bearings - University of Caridge
Taper roller bearings take this concept further by making the rings and rollers tapered, to increase the contact area, permitting large radial and thrust loads. They are for this reason used in some helicopter transmissions to take advantage of their greater load capacity for a given shape or weight when compared with ball or cylindrical roller bearings [ 7 ].
