This utility model provides a magnetic levitation low-friction dual-hub device suitable for heavy-duty medical equipment, belonging to the technical field of hub devices. This magnetic levitation low-friction dual-hub device for heavy-duty medical equipment includes an outer load-bearing hub, an inner drive hub, radial ceramic bearings, and an axial magnetic levitation module. The outer load-bearing hub is sleeved on the outside of the inner drive hub. The radial ceramic bearings are disposed between the outer load-bearing hub and the inner drive hub, and are connected to the inner wall of the outer load-bearing hub and the outer wall of the inner drive hub, respectively. The axial magnetic levitation module is disposed at the end of the outer load-bearing hub away from the radial ceramic bearings, and is connected to the end of the outer load-bearing hub. This invention solves the problems of high friction coefficient, high movement resistance, heavy operating burden for medical personnel, and difficulty in meeting the frequent movement requirements of traditional heavy-duty medical equipment hub systems.
