Bearing type is the air-bearing kinds, "Micro Cooling Fan" is used. In mechanical engineering, bearing the type shaped very much, but the radiator products will then use categories: use of sliding friction sleeve bearings and ball bearings use rolling friction bearings and mixed in the form of two of these three. In recent years, the major "Micro Cooling Fan" radiator manufacturer in terms of the launch of new bearing technology, such as magnetic bearing, water bearing, core bearing, to Fu bearings are also on top of the basic form of the bearing to be improvements made, principle of operation is not changed.
