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.

Roller Bearings Selection Guide: Types, Features, Appliions | …

Roller Bearings Information. Roller bearings are used to replace sliding movement with low friction, rolling motion in rotary appliions. The principal types of roller bearings are cylindrical, spherical, and tapered. In general, roller bearings offer higher load capacities than ball bearings of the same size.

Single row tapered roller bearings | SKF

SKF single row tapered roller bearings are designed to accommodate coined loads, i.e. simultaneously acting radial and axial loads.The projection lines of the raceways meet at a common point on the bearing axis (apex point A, fig. 2) to provide a true rolling action and therefore low frictional moments during operation.

Bearing Arrangement - an overview | ScienceDirect Topics

Thrust bearing, Fig 3.12A, composed of bearing balls supported in a ring, these can be used in low thrust appliions where there is relatively small axial load, but are susceptible to radial loads. Tapered roller thrust bearings, Fig 3.12B, consist of small tapered rollers arranged so that their axes all converge at a point on the axis of the bearing.
