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.
