Identification of fan bearings on the market

Radiator development has been accompanied by two major themes - cooling and mute. The easiest way to improve the heat dissipation performance is to increase the fan speed. As the fan speed increases, the noise also increases. At this time, the noise comes from two aspects. On the one hand, the sound of cutting the air when the fan is running, and the other is the sound generated by the friction of the fan mechanical equipment. This sound is emitted from the bearing. Some radiators with poor quality often result in poor use of the fan. If you buy that kind of product, it may take a long time to enjoy the horrible noise caused by the bearing.

From this, how important the bearing as an important part of the fan is to our radiators. These fan bearings are more common in the market. Let's take a look:

1. Oil bearing Sleeve Bearing

Oil bearing Sleeve Bearing: This type of bearing can be said to be the older bearing technology on the market. However, due to its low cost, it is technically easy to implement. Many products, including well-known brands, are still in use. The advantage is that it is initially used. Quiet, low noise, low price; but generally in the later period due to the internal fuel volatilization and the ingress of dust, causing serious wear on the bearing, resulting in slower speed, increased noise, and an average life of only 8,000 to 15,000 hours.

2, Laifu Bearing Rifle Bearing

Rifle Bearing: Rifle Bearing Technology developed by CoolerMaster uses a shaft core with a reverse spiral groove and a slinger. When the fan is running, the oil will form a reverse migration, thus avoiding oil loss and acting as an oil bearing. The modified type, the Laifu bearing effectively improves the service life of the bearing. Compared with oil-bearing bearings, there is not much improvement in cost. It can be said that it is a relatively good economic solution in the middle of low-end products.

3, magnetic suspension hydraulic bearing HYDRAULIC Bearing

Magnetic suspension hydraulic bearing HYDRAULIC Bearing: The magnetic suspension hydraulic bearing technology introduced by AVC utilizes the magnetic support suspension function and the special oil film lubrication matched with it, which effectively solves the contradiction between the long life and low noise of the fan.

4, nano bearing NACOOL Bearing

Nano-bearing NACOOL Bearing: Introduced by FOXCONN, the new bearing material made of nano-composite has good performance in high temperature and wear resistance. This kind of bearing can effectively improve the anti-wear ability of the fan bearing, and it is complicated. It will not be affected too much in the environment, and the service life will be increased to 120,000~150,000 hours compared with ordinary bearings.

5, ball bearing BALL Bearing

Ball bearing BALL Bearing: Compared with oil-impregnated bearings, ball bearings change the friction mode of the bearing. This method is more effective in reducing the friction between the bearing surfaces, effectively improving the service life of the fan bearings, and thus cooling The service life of the device is extended. The disadvantage is that the process is more complicated, resulting in higher costs and higher operating noise.

6, double ball bearing DUAL BALL Bearing

Double ball bearing DUAL BALL Bearing: The ball bearing also includes double ball bearing. Compared with the single ball bearing, the double ball bearing can last for more than 50,000 hours. The stability is very good, but it brings higher work. Noise and manufacturing costs.

There are different differences between the radiator products using these bearing technologies on the market. The simplest is the difference in price. Understanding these differences can help us decide when we purchase the radiator, and also according to our own needs. Avoid some merchants shoddy, let yourself spend money and can not achieve the effect you want.
