The double ball bearing (2 Ball Bearing) is a relatively high-grade bearing. It adopts the form of rolling friction. It adopts two ball bearings. There are several tiny steel balls around the shaft. When the blade or shaft rotates, the ball rotates. . Because they are all spheres, the friction is small and there is no problem with oil leakage. The advantage of the double ball bearing is that the life is very long, about 50,000-100,000 hours; the anti-aging performance is good, and it is suitable for the fan with higher rotation speed. The disadvantage of double ball bearings is the high manufacturing cost and the highest noise at the same speed level. Double ball bearings and hydraulic bearings have better sealing, especially for double ball bearings. The double ball bearing is entirely embedded in the fan, and the rotating portion is not in direct contact with the outside. In a sealed environment, the working environment of the bearing is relatively stable.
Features Maintenance-free double ball bearing, long service life, sufficient airflow and wind pressure
