A magnetic bearing device and a positioning system which includes the magnetic bearing device are provided. The magnetic bearing device comprises a stator and a moving member which are formed from a coil device with at least one coil body, magnets, and/or flux guide members, where the moving member is movable relative to the stator along a direction of motion and the stator and the moving member are configured such that a magnetic force can be exerted upon the moving member when electrical energy is applied to the coil device to form an air gap between the stator and the moving member. The coil device is arranged exclusively in the stator and the extension of the moving member in the direction of motion is smaller than the extension of the stator in this direction. The extension of the stator corresponds to the length of the at least one coil body.
