Performance comparison of common bearings for cooling fans

Fan bearings are very important in the cost and performance of the entire fan. In this chapter, we discuss several common fan bearings on the market. With continuous improvement and perfection, a huge family of oil-impregnated bearings has been able to meet the needs of mainstream applications. Currently, the most widely used hydraulic fan has a life span of between 30,000 and 50,000 hours, which is fully capable of meeting common application requirements. The mute effect is obviously better than that of a ball fan, so players do not need to blindly pursue a ball fan when buying a fan. Moreover, the technical difficulty of the ball fan is relatively high, and the price is also more expensive. However, for players who are pursuing longevity, you might as well buy a double ball fan. For players who pursue ultra-quietness, average life expectancy, and temperature not higher than 60 degrees, it is better to purchase JAMICON flywheel bearing fans and magnetic levitation fans. Compared with double ball bearings, the price will be cheaper. Some, compared with oil-impregnated bearings, its life can be guaranteed. u003cbru003e u003cbru003e u003cbru003e Oil content 15,000-30,000h u003cbru003e u003cbru003e u003cbru003e Single ball 30,000-40,000h u003cbru003e u003cbru003e u003cbru003e Double balls 50,000-100,000h u003cbru003e u003cbru003e u003cbru003e Hydraulic pressure above 50,000h u003cbru003e u003cbru003e u003cbru003e Flywheel 50,000h or more u003cbru003e u003cbru003e u003cbru003e Magnetic levitation 50,000h or more u003cbru003e u003cbru003e u003cbru003e Fluid dynamics 50,000h or more u003cbru003e u003cbru003e u003cbru003e u003cbru003e u003cbru003e u003cbru003e u003cbru003e Thank you for your reading.
