单排四点接触球式回转支承由两个座圈组成，结构紧凑，重量轻，钢球与圆弧滚道四点接触，能同时承受轴向力，径向力和倾翻力矩，回转式输送机，焊接操作机，中小型起重机和挖掘机等工程机械均可选用。

The single row four point contact ball type slewing support consists of two seat rings, with a compact structure and light weight. The steel ball contacts the circular arc raceway at four points, and can withstand axial force, radial force, and overturning moment simultaneously. It can be used in engineering machinery such as rotary conveyors, welding operators, small and medium-sized cranes, and excavators.
