The utility model discloses to a plane revolving member and relates to the technical field of plane revolving members. By utilizing the plane revolving member, the technical problems that the existing aluminum and plastic plane revolving members are light in weight and not durable, an upper cover and a lower cover fall off constantly and revolving is not flexible are overcome. The plane revolving member comprises an upper cover, wherein the upper cover is connected with an inner bearing ring; the inner ring is in movable connection with an outer ring by marbles; the outer ring is connected with a lower cover; the upper cover and the lower cover are made of metal materials; the upper cover and the inner bearing ring are welded by a welding machine to be connected; and the outer ring and the lower cover are welded by the welding machine to be connected. Because the plane revolving member is welded by the welding machine, welding is firm, stability is good, revolving is flexible, and use is safe and reliable.
