Bearing form is air-cooled radiator fan bearing shape. In mechanical engineering, bearing type is very much, but also in the radiator so few: the use of sliding friction sleeve bearing and rolling friction ball bearings and two bearings the form of hybrid of these. Major radiator manufacturers in recent years bearing aspects of launch of the new technology, such as magnetic bearing, water bearing, bearing core, to the blessing bearings are also made ??bearings to improve the basic form of the above with the principle of operation does not change to . Ordinary air-cooled radiator, oil bearings and ball bearings.

The oil bearing is the use of sliding friction sleeve bearings, the use of oil as a lubricant and DRA, the initial use of low noise operation, low manufacturing costs, but this serious bearing wear life than ball bearings are a lot worse. These bearings use over time, due to the oil seal (computer radiator products are not to use high-grade oil seals in general is ordinary paper, oil seals), the lubricant will gradually evaporate, and the dust will enter the bearing. Causing slower fan speed, noise increases and other issues, but also serious cause severe vibration caused by fan bearing wear eccentric. These phenomena, either to open the oil seal oil, or only out to purchase another new fan.

Ball bearings to change the bearing friction, rolling friction, and this more effective way to reduce friction between the bearing surface phenomenon, effectively increasing the life of the fan bearings, and thus extend the life of the radiator. The drawbacks that the process is more complex, leading to cost increase, it also brings higher noise.
