Wind energy
In usually, the wind-energy system is bad, with more dusty, strong corrodibility, high temperature difference and difficult to maintenance. So the life time of slewing bearing is required to at least 20 years.
The wind-energy slewing bearing is divided 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.
As leading supplier of Blade and Yaw bearings for wind energy, we can supply you with suitable products-individually to meet your requirement-wherever you need them for diameter of up to 8000mm.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
Many years of experience and skill in dimensioning ball and roller slewing connections enable us to provide optimal designs for the loads and operating condition.
Solar Power Generation
Solar power generation, also called optical or photovoltaic power generation, is the new clean energy developed all over the world with a promising future. The solar cell panel of the solar power generation system needs to change its angle according to the position of the sun to collect the solar rays and heat for a high generating efficiency. We carefully design and develop a turning pair with external-gear bearing sealed in the wheel for the sun tracing machine. The external gear fits tightly with the secondary conjugate screw teeth. Droved by the servo engine, the worm rotates with the external gear. With high strength screw, the solar panel is connected with the worm-gear pair.

Slewing bearings are large-sized bearings specifically designed to accommodate oscillating movements. They are comprised of an inner ring and an outer ring,one of which usually incorporates a gear. The bearing raceways, in conjunction with the rolling elements (and cages or spacers), are designed to accommodate loads, acting singly or in combination, and in any direction.
Integral synthetic rubber seals effectively protect the bearing from the ingress of foreign matter, as well as prevent the escape of grease. Compared to the traditional pivot arrangement, slewing bearings have many design and functional advantages.
The assembly is much more compact and its hollow centre permits the installation of driving mechanisms and the passage of various control devices; the superstructures of the rotating part are more easily accessible. The small difference in height between the geared ring and un-geared ring reduces the overhang of the driving pinion.
