There are many factors that determine the noise level of the fan, including fan speed, fan size, dynamic balance of the fan, use environment... Wait a minute. One of the most important factors is the type of fan bearing, so how should the cooling fan bearing be choose?

Case Details

The application fields of cooling fans are very wide. Different fields have different requirements on the air volume, wind pressure, noise and life span of cooling fans. Let's take a look at several commonly used bearings that affect the main performance of cooling fans:

1. The performance is not high, the noise is small, and the price is low. Hydraulic bearings are improved on the basis of oil bearings. The hydraulic bearing adopts a unique ring-type oil supply circuit, which has reached 30,000 hours and has inherited the advantages of oil-impregnated bearings. After a period of use, the noise may gradually increase, so you need to be prepared for maintenance or replacement.

2. High cost and long life. The double ball bearing adopts two ball bearings. There are several tiny steel balls in the bearings around the axis. When the fan or the axis rotates, the steel balls will rotate accordingly. Because they are all spheres, the friction force is small and there is no oil leakage. The problem. The service life reaches 50,000 hours to 100,000 hours.

3. There are no special requirements for performance and noise, but long service life and low price are expected. Improved oil-impregnated bearings such as Laifu and Hypro bearings are all options worth considering.

4. Good performance, low noise, and long life, so that no further requirements can be placed on the price. As long as the funds are sufficient, special bearing technologies such as precision ceramics can be included in the selection range.

In general, a good fan, in addition to its large air volume and high wind pressure, its own reliability is quite important, and the bearings used by the fan play a very important role.

However, those with sealed components, including motors, controllers, and connectors, can also be operated outdoors. Performance IC forklifts tend to be utilized in heavy-duty applications, such as brick and lumber yards, where larger capacity and performance is required to move the heavy loads.
