Why it is said that the quality of the bearing of the cooling fan directly determines the length of life

Looking carefully at the specifications provided by the cooling fan manufacturer, it is not difficult to find that the lifespan of the two different bearings, namely the ball bearing and the oil-impregnated bearing, is twice as long. The ball bearing has a unique structure, stable quality and long life. What we want to share here is the oil-impregnated bearing. The advantages and disadvantages of the oil-impregnated bearing have a great impact on the life of the cooling fan. Friction occurs between them, causing abnormal noise, which affects the life of the cooling fan. In addition, alloys such as copper, aluminum, copper and iron have poor oil storage capacity. The precision and size of the fan are unreasonable. When the cooling fan is running, there will be a grunt between the shaft core and the bearing, which will cause the fan blades to run unbalanced and the life will be short. The best cooling fan in China is the copper shaft of Taiwan, which has relatively high precision and relatively good oil storage capacity. The hydraulic bearing of Panasonic in Japan has a longer life. The oil bearing of the cooling fan manufacturer is imported from Taiwan.
