Ball bearings are generally used in low-load mechanical transmission equipment. Because the bearing area of ball bearings is small, serious mechanical damage is prone to occur under high-speed operation. Therefore, needle roller bearings are often used in heavy-load mechanical transmission to increase the bearing surface, improve mechanical transmission efficiency, and reduce Mechanical damage.
The ball bearing changes the friction method of the bearing and adopts rolling friction. This method more effectively reduces the friction phenomenon between the bearing surfaces, improves the service life of the fan bearing, and therefore extends the service life of the radiator. The disadvantage is that the process is more complicated, the cost is increased, and it also brings higher working noise.
