High-speed "Cooling Fan Manufacturer" Always use low speed fan uses ball bearing low-cost oil bearing. Oil-bearing fan with only one bearing; and require two ball-bearing fan bearings, single ball bearing, is "1Ball + 1Sleeve", still with the oil-bearing components. Oil-bearing fan used copper-based sintered powder made by using lubricating oil bearings need to reduce the number of sliding friction, by lithium grease lubricating oil system Stuttgart modulation. "Cooling Fan Manufacturer" With the long run, the oil inside the bearing will evaporate and dry, the friction coefficient increases, fan operation affected may appear different sound, speed Pianman not even turn on. The ball bearing replaced by rolling friction sliding friction, low coefficient of friction and to overcome the shortcomings of the friction coefficient tends to become, and therefore "Cooling Fan Manufacturer" higher driving stability, lifetime is relatively much longer.
