| Performance characteristics: variable pitch bearings are installed on the roots of the blades of wind turbines and bear the axial forces, radial forces and overturning moments generated by blades and wind sweeping through the blades. Variable pitch bearings have self sealing, corrosion resistance, and have a certain pre tightening. Bearing in complex load conditions, in the wind, rain, dust, salt fog, high and low temperature and strong ultraviolet and other extremely harsh environment, with more than 20 years of service life and more than 99% of the reliability. |
