The invention relates to a universal wheel set and a suitcase. The universal wheel set can comprise a base structure and a wheel ball, wherein the base structure comprises an upper base and a lower base, a cavity can be formed by the upper base and the lower base in an enclosed mode, and the wheel ball can be locked in the cavity in an omnidirectional rolling mode. The bottom of the lower base is provided with an opening, wherein the opening makes a part of the wheel ball protrude out of the lower end face of the lower base, so that an exposed rolling ball surface is formed. The inner diameter of the opening is smaller than the diameter of the wheel ball. According to the technical scheme, the strength of the wheel set can be improved remarkably, and the service life of the wheel set is prolonged.
