Spherical roller bearing for wind turbine main shafts
Spherical roller bearing for wind turbine main shafts are optimized to handle the varying direction and high thrust loads of wind energy applications, allowing to perform more reliably under typical operating conditions. A modified inner geometry with super-finished functional surfaces makes this possible. Using a one-piece roller-guided cast-iron cage and an enlarged lubrication groove increases robustness.

Improved performance under wind operating conditions
Accommodate misalignment
Up to twice the fatigue life
Increased robustness for both radial and axial load conditions
Improved lubrication
