There are many patented bearings for cooling fans. The hydraulic bearing and oil-retaining bearing we are going to talk about today are two commonly used bearings. The bearings look similar, so what is the difference between them?
First of all, as far as we know, the hydraulic bearing is a patented bearing of Panasonic. The sound of this copper shaft is relatively small. It is said that the cooling fan has a long life and the price is very expensive. The material of the hydraulic bearing fan currently made in our country is the same as that of the oil-impregnated bearing. The outer frame is made of one-piece structure, which is very similar to the shape of Panasonic. In fact, the cost is almost the same as that of the oil-impregnated bearing.
Because of the integrated structure of hydraulic bearings, it is not convenient to disassemble and repair. If there are defective products in the process that need to be repaired, it is very inconvenient. In addition, some fans will be scrapped when the product assembly size is adjusted before production. Therefore, hydraulic type Cooling fans generally require orders above 3K.
Regarding the performance of the product, the oil-contained cooling fan is not much different from the hydraulic type. Because the bottom of the hydraulic bearing is sealed, the temperature resistance is stronger and the life is relatively longer.
