A ball bearing bracket fan is a type of fan that uses ball bearings to support the windshield and can be used in portable products in different orientations and angles. Advantages include long life and easy activation, but disadvantages include fragility, high price, noise, difficult assembly, and unmanageable sourcing and quantity requirements. Ball bearing bracket fans are usually used in equipment with low load mechanical drives, while needle bearings are often adopted in heavy load mechanical drives.

Ball bearing bracket fans work by using ball bearings to support the fan shroud, allowing it to rotate freely in different directions. This design improves the stability and reliability of the fan and also reduces fan vibration and noise.

The advantages of ball bearing support fans include:

1. High stability: Ball bearing bracket fans use ball bearings to support the fan shroud, which can rotate freely in different directions, thus improving the stability and reliability of the fan.

2. Low noise: ball bearing bracket fan adopts ball bearing to support the windshield, which can reduce the vibration and noise of the fan, thus improving the comfort of using the fan.

3. Long service life: The ball bearing bracket fan adopts ball bearings to support the windshield, which can improve the service life of the fan and thus reduce the maintenance cost of the fan.

4. Strong adjustability: The fan shroud of the ball bearing bracket fan can be rotated freely in different directions, so that the direction and angle of the fan can be adjusted according to the needs.
