Double row ball slewing bearing
The double-row ball slewing bearing is composed of two rows of ball rolling elements, which can bear large axial load, radial load and overturning moment at the same time, and has a higher safety factor. It is widely used in medium and large cranes, mining equipment, excavators and other mechanical equipment. The double-row ball slewing bearing is mainly composed of an inner ring, an outer ring, two rows of rolling elements (steel balls), a cage and a sealing device. The inner and outer rings usually have multiple mounting holes for fixing to the equipment. The rolling elements roll between the inner and outer rings under the guidance of the cage or isolation block to ensure smooth rotation.
