SKF has launched  its new spherical roller bearings for wind turbine main shafts. Features not needed in this sector, such as the ability to handle speeds up to 600 r/min, have been eliminated to focus on those that are, including improved radial and axial robustness.

The adapted design of the heavy duty bearings includes a significant weight reduction, an optimised internal geometry and improved lubrication capabilities to ensure lower contact pressures and enhanced load carrying capacity.
