wind power bearing and bearing for yaw gear box

Due to yaw gear box requirements for small and large torque transmission, so the deck crane bearing is also pursuing a small design and high load capacity. Therefore, the raceway ring use thin-wall angular contact ball bearings and taper roller bearing .

If the angular contact ball bearing load large axial load, it is necessary to improve the inner ring andouter ring raceway groove rib height, as a special design to increase the allowable axial load.Compared with the yaw gear box for special products and standard products, ensure Gao Rongxuaxial load of about 9 times（wind power bearing）.
