Magnetic bearing - Wikipedia

A magnetic bearing is a type of bearing that supports a load using magnetic levitation.Magnetic bearings support moving parts without physical contact. For instance, they are able to levitate a rotating shaft and permit relative motion with very low friction and no mechanical wear. Magnetic bearings support the highest speeds of any kind of bearing and have no maximum relative speed.
