Ball bearing (2 Ball Bearing) belongs to the bearing relatively high-grade, rolling friction form, using two ball bearings, Zhou Chengzhong several tiny ball around the axis, when the fan page or axis rotates, the steel ball is followed to rotate. Because it is a sphere, so the friction force is small, and don't have a problem with oil. The advantages of dual ball bearing is long life, about 50000-100000 hours; anti aging performance is good, suitable for fan rotation speed v high. Double ball bearing fault is high in manufacturing cost, and at the same speed under the maximum noise level. Closed double ball wind bearing and hydraulic bearing is better, especially the double ball bearing. Double ball bearing is the entire block in the fan, the rotating part is not in direct contact with the outside world. In a sealed environment, bearing more stable working environment.
