In the bearing industry bearing type are many, NSK bearing type but on the radiator of the few, a few possible: sleeve bearings, ball bearings, magnetic bearings, bearings, bearings and magnetic wave.
The magnetic bearing, magnetic bearing, water bearing, sleeve bearing is also improved from the above two kinds of sleeve bearing and rolling bearing, the working principle and did not change. NSK bearings are now mainly used air-cooled radiator of ordinary oil bearing and ball bearing.
Oil the bearing sleeve bearing sliding friction is used, the use of oil as a lubricant and drag reduction agent, with low noise, low manufacture cost, but bearing wear serious, life of ball bearing is much lower than. And the NSK bearing is used for a long time, due to reasons of lubricating oil seal will gradually volatile, dust will enter the bearing inside, will cause the fan speed is reduced, increased noise and other issues, but also seriously because the bearing wear caused by fan eccentric triggered violent vibration. Influence of the service life of bearing.
Ball bearing changes the friction mode of NSK bearings, by using the method of rolling friction, this way is more effective to reduce the frictional resistance of bearing, effectively improve the service life of the fan bearings, thus prolonging the service life of the radiator. Is the manufacturing process is more complex, increasing cost.
Type NSK bearing the radiator often use is about these, when in use must choose the suitable bearing, and do the maintenance work, prolong the service life and reduce the production cost.
