Bearing arrangements for wind turbine main shafts | SKF | SKF

Different turbine manufacturers have different design philosophies that influence which bearings they use. One set-up is ‘loing and non-loing’, which uses two separate bearings on the main shaft. A loing bearing is exposed to both radial and axial loads, while a non-loing bearing accommodates only radial loads.
