The difference between the fan bearing

The radiator development has been accompanied by two themes - — Heat dissipation and mute. To improve the heat dissipation performance, the simplest way is to improve the speed of the fan, fan speed increase after noise followed. The noise comes from two aspects, on the one hand is the fan operation when cutting the whir of the air, on the other hand is a fan of the sounds made by friction, mechanical equipment of the voice is a bearing. Some radiator quality closes nevertheless, often caused by the use of a fan, if you buy the product, may be able to enjoy it won't be long before bearing from the horrors of the noise. Thus, as an important component of the fan bearing radiator how important for us, these fan bearings are common in the product on the market, we take a look at: 1, the oil-retaining bearing SleeveBearing oil-retaining bearing SleeveBearing: this type of bearings is now in the market are older bearing technology, but due to the low cost, easy to implement on the technology, many products including well-known brands have continued to use, its advantage is the early use of quiet, low noise, low price; But generally arrived late due to the internal oil volatilization and the entry of dust, causing severe wear of bearing, leading to speed slow, noise increases, the average life expectancy is only 8000 ~ 15000 hours. 2, rifle bearing RifleBearing rifle bearing RifleBearing: research and development by CoolerMaster rifle technology USES a reverse spiral groove bearings and gear oil groove of the shaft core, oil will form a reverse migration when the fan is running, so as to avoid loss of oil, as to change the type of oil bearing, bearing rifles effective promoted the service life of bearing. And also compared with that of oil bearing from cost, not how to ascend, can be said to be among the low-end products a relatively good economical solution. 3, hydraulic magnetic levitation bearing HYDRAULICBearing maglev hydraulic bearing HYDRAULICBearing: cooked up by AVC suspension hydraulic bearing technology using backed magnetic levitation effect and cooperate with the special oil film lubrication, effectively solves the long service life and low noise fan the contradiction between the two. 4, bearing NACOOLBearing nano bearing NACOOLBearing: launched by FOXCONN, nano-meter composites made of new bearing materials have good high temperature resistance, wear resistance, the bearing can effectively improve the wear resistance of the fan bearing, and use in complex environment will not be affected by too much, increase service life than ordinary bearing to 120000 ~ 150000 hours. 5, ball bearing BALLBearing ball bearing BALLBearing: compared to oil bearing, ball bearing has changed the way of bearing friction, this way is more effective in reducing the friction between the bearing surface phenomenon, effectively improve the service life of the fan bearing, thus to extend the service life of the radiator. The downside is that technology is more complex, lead to cost increase, at the same time also bring higher noise. 6 dual ball bearing, double ball bearing DUALBALLBearing DUALBALLBearing: include double ball bearing in the ball bearing, compared with a single ball bearing, double ball bearing service life can reach more than 50000 hours, the stability is very good, but the noise and the manufacturing cost is higher. Using these bearing technology radiator products on the market have different differences between their respective the simplest is the price difference, understanding these differences can help us when the choose and buy radiator according to their own needs to decide, but also avoid partial businessman shoddy, took his money but can't reach the effect you want.
