It is comprised of double row steel balls in upper and lower layers, inner ring and outer ring, spacer, lubricating and seal fittings. The inner ring and outer ring are in two separate structures and two half rings need to be fixed by joint bolts. Due to the upper and lower rows of steel balls, the bearing can carry radial force, axial force and...

 slewing bearings are extensively applied in such industries as metallurgy, vessel, oil, chemistry, mine, coal, hydroelectric power, port machinery, heavy machinery and aerospace or some other...

Four-point contact ball slewing bearing is composed of 2 seat-rings, Its features compact in design, and light in weight. The balls contact with the circular race at four points via which the axial force, radial force and resultant moment maybe born simultaneously. It is mainly used for slewing conveyers, welding arm and positioner, medium duty...

These bearings applies to wind turbines, or wind power, in general, there are three types, yaw bearings, blade bearings/pitch bearings, shaft bearings.  Wind power bearings are widely used, for the purpose of energy conservation and environmental protection. Wind power bearings have a complete technology and processing,and need a strict...
