What are the characteristics of the cooling fan ball bearings?

What are ball bearings and what are the characteristics of ball bearings for cooling fans? The following Ruiapple cooling fan manufacturer will introduce to you in detail, the details are as follows:

Ball bearings are operated with round metal balls, which belong to point contact, so it is easy to activate the operation. In addition, the ball bearing is used in conjunction with the spring, so the metal ring outside the BallBear is supported by the spring, so that the weight of the entire fan rotor rests on the ball bearing and is indirectly supported by the spring, so it can be used in different directions , Angle portable products, but still must prevent falling to avoid damage to the ball bearings, which may cause noise and reduce service life.

What are the characteristics of the cooling fan ball bearings?

Advantages of ball bearings:

1. The metal bead movement belongs to point contact, so it is easy to activate the movement;

2. Longer service life (compared with oil bearing;

3. It can be used for portable products that are often operated at different placement angles and directions (but to prevent random falling or falling);

Disadvantages of ball bearings:

1. The bearing structure is quite fragile and cannot accept the impact of external forces;

2. The price is high, unable to compete with the oil bearing in the interest price;

3. When the motor is rotating, the rolling of the metal ball will produce louder noise;

4. The ball bearing uses the elasticity of the spring to make its positioning, making it difficult to assemble;

5. The source and quantity requirements of ball bearings are not easy to control;

It can be seen from the above introduction: Ball bearings are generally used in low-load mechanical transmission equipment. Because the bearing area of ??ball bearings is small, severe mechanical damage is prone to occur under high-speed operation, so needle roller bearings are often used in heavy-load mechanical transmission to increase the bearing surface, improve mechanical transmission efficiency and reduce mechanical properties damage.
