The pivot bearing of wind power equipment usually needs to carry large axial force, radial force and tipping torque, so a larger pivot bearing is usually required.
The pivot bearing on the upper end of the column mainly plays the role of steering control, and the pivot bearing is driven by the gear.
Because wind power must withstand large axial force, radial force and tipping torque, and requires small clearance and durability, the large-sized slewing bearing using 42CrMo material can meet the requirements of stability, long service life and large bearing capacity.
