YDTech® manufacturer of wind power bearing include yaw(pitch,dynamo,mainshaft,gear box) bearings combination! supplier of wind power (pitch,yaw,dynamo,mainshaft,gear box)turbine bearing in china.

we had developed the wind power bearing, including pitch bearing, paw bearing, dynamo bearing, mainshaft bearing and gear box bearing. such bearings have the high carrying capacity and the long period of validity, security, high antisepticise and sealed, our product passed the charpy impact test and got the china classification society certification.

slewing bearing with internal and external teeth should go on a gear milling before grinding process according to the technological requirements strictly and precision grade reached technological requirements.

fixing the position according to the drawings and inspecting dimensions correctly and then drilling. Mounting hole in slewing bearingwhich the inner ring and outer ring separated must be combinated together to process and the interval must be 180C from soft zone, distance tolerances between mounting holes should not be over than 5‰.
