      1 Sleeve Bearing
Sleeve Bearing is the use of a cooling fan bearing is most common. It is the use of oil as a lubricant and drag reduction agent, advantage is the price is very low, initial use relatively low running noise. Disadvantage is the bearing is easy to wear, short life. In addition, the bearing is used for a long time, the lubrication oil in the bearing sleeve easy leakage, noise increases, and pollution and other accessories.
2 Dual Ball Bearing orTwo Ball Bearing
Dual Ball Bearing orTwo Ball Bearing using two ball bearings, sliding friction to rolling friction instead of traditional use, so the friction force is small, do not need lubricating oil, no oil leakage problems. It has the advantages of long service life, against the aging performance is good, suitable for high speed fan. Disadvantage is high cost, and the maximum noise.
3.ONE Ball Bearing or Ball + Sleeve Bearing
ONE Ball Bearing or Ball + Sleeve Bearing is an improvement on the traditional bearing, the sliding and rolling form mixed friction, a ball bearing and a bearing to reduce the cost of double ball bearing. Set the advantages of bearings and double ball bearing, the shortcomings in the ball after the addition, the operation noise increased, but still less than double ball bearing.
4.Hydraulie Bearing
Hydraulie Bearing is improved based on the bearing. Hydraulic bearing adopts a ring type oil circuit is unique, largely reduce the leaking problem, life than ordinary oil bearing greatly extended, and has inherited the bearing: operation noise is small, the hydraulic bearing has been in the AVC radiator has been used widely in the.
5.Rifle Bearing
Rifle Bearing is mainly used for cooling fan CoolerMaster, is an improvement to the traditional bearing. Rifle bearing wear-resistant material made of high oil hollow bearing, shaft core is also provided with a reverse spiral groove and gear oil groove. In fan operation, lubricating oil which will form a reverse flow, thus avoiding the problem of oil leakage, and the running noise control very small.
In addition, and NACOOL Bearing), NANO Ceramic Bearing, Magnetic Bearing Hypro Bearong and so on.
