High quality ball slewing bearings Composed of rolling elements maintaining separation between the inner and outer rings of a bearing, ball bearings allow for smooth, high-speed motion and reduced friction. Able to sustain both radial and axial loads, they can be developed for many different applications, load types, and speeds. Xuzhou Fenghe Intelligent Technology Co., Ltd. specializes in six types slewing bearings, including single-row ball type, double-row ball type, three-row roller type, single-row cross roller type, double-line ball type and ball-roller combined type. Ball bearings are usually made of stainless steel, ceramic, or chrome steel, but material and overall design can vary widely depending on the specific job at hand. Flange, cages, and multiple bearing rows can also be included to allow for higher performance in order to meet specific application needs.
