Sunlight-generator: In sunlight-generator system, the solar panel need to rotate uper and lower, left and right with the position of the sunligh in order to get more power. SBI specially design the slewing bearing SIR20/1166 support that can dustproof and continuously running long time.

SBI new research and design the worm slewing driver, motor slewing driver used to the solar trackor system.

Successful case: slewing bearing for one sunlight power company
Type: SIR20/1166

Application: worm slewing driver, slewing bearing

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.

SBI supplied high quality bearing to Themal power industry, including deep groove ball bearing, symmetrical spherical roller bearing, cylinder roller bearing, taper roller bearing and thrust roller bearing. We continuously to develop the design and technique so that to prolong the life time of the bearing and increase the capacity of the equipment according to the bad working condiction of coal mill, conveyor and crusher with dusty, high temperature and low lubrication.
Successful case:
1.Power plant stacker-reclaimer used slewing bearing.Type: SBI-202A
2. Coal mill used taper roller bearing.Type: HH953749/10
   Bearing application: Slewing Bearing, taper roller bearing, angular contact ball bearing, deep groove ball bearing and symmetrical spherical roller bearing.
