Double ball bearing (2 Ball Bearing) is a high-grade bearing, which takes the form of rolling friction. It uses two ball bearings. The bearing is surrounded by several small steel balls on the shaft. When the fan page or the rotating shaft rotates, the steel ball is Rotate. Because it is a sphere, there is less friction and no oil leakage problems. The double ball bearing has a long service life, with a service life of about 50,000-100,000 hours; good anti-aging properties, suitable for transfer v high-speed fans. The disadvantage of double ball bearings is the high manufacturing cost and maximum noise level at the same RPM. Double ball bearings of wind and hydraulic bearings are better, especially double ball bearings. The double ball bearing is integrally embedded in the fan, and the moving parts are not in direct tell with the outside world. In a sealed environment, the working environment is relatively stable.

With maintenance-free ball bearings, it has dual functions, long service life, and sufficient cooling air flow and air pressure.
