    In usually, the wind-energy system is bad, with more dusty, strong erodibility, high temperature difference and difficult to maintenan. So the life time of slewing bearing is required to at least 20 years. The wind-energy slewing bearing is devied into : yaw bearing (slewing bearing), Pitching Bearing (slewing bearing), generator bearings(cylinder roller bearing, angular contact ball bearing), Gear box bearing( cylinder roller bearing，deep groove ball bearing ), spindle bearing ( symmetrical spherical ) etc. 
    

    SBI wind-energy slewing bearing designed with better structure and small clearance.  We usually select material 42CrMo, by whole quenched and tempered. The slewing bearing can endure low temperature impact with longer life time. We also select dust seal, zinc plating to the surface, painting spray to guarantee the corrosion resistance and the life time for 20 years.
    
Successful case:  REPOWER 1.5MW PITCHING BEARING
    
Bearing application: Slewing Bearing, cylinder roller bearing, angular contact ball bearing, deep groove ball bearing and symmetrical spherical.
