Double-row ball slewing bearing (external tooth type)
Double-row ball-type slewing bearings consist of two rows of ball rolling elements, enabling them to simultaneously withstand significant axial loads, radial loads, and overturning moments, with a higher safety factor. It is widely used in medium- and large-sized cranes, mining equipment, excavators, and other types of machinery. Double-row ball slewing bearings primarily consist of an inner ring, an outer ring, two rows of rolling elements (steel balls), a cage, and sealing devices. Its inner a
