the fan bearing system generally suggest zui good use ball bearings, because the life of heat fan fan often depends on the reliability of the bearing, ball bearing system has been proved to have the characteristics of rate and low calorific. Ball bearing rolling friction, the metal bead rolling, contact surface is small, small friction coefficient; And oil bearing for sliding friction, contact area is large, use for a long time, after oil volatilization, bearing is easy to wear and friction coefficient is big, the noise caused by the late life is short. Used in fan oil bearing the copper base powder sintering and become, use oily add lubricating oil to reduce the number of sliding friction bearing and lubricating oil by lithium grease and oil special modulation. With long time of operation, the bearing inner oil can evaporate and dry, the friction coefficient increases, fan operation affected, may appear different sound, speed slow don't even turn phenomenon. And ball bearing replaced by rolling friction for sliding friction, low friction coefficient and overcomes the drawback of the coefficient of friction can become, and running stability is strong, relatively is much longer service life.
