Many second-tier cooling fan manufacturers have cooling fans with a hydraulic bearing structure. Some manufacturers even say that the hydraulic structure of the fan is similar to the double ball bearing. Is it really that good? Let’s share that the hydraulic bearing is a patent of Panasonic, and the price on the market is also very high. It is higher than the price of our domestic double ball bearing, but it does have a long life and quiet sound. It is also a copper bearing, but There are almost no agents directly selling this kind of bearings in China. The domestic hydraulic bearing is a bit similar in appearance to Panasonic. It is integrally formed by injection molding at the label and does not need a fuel cap. The salesman will say that this structure has the effect of preventing dust and oil leakage. In fact, we can turn on a cooling fan and take a look, and you will find that the oil will not leak from the label, but after a period of operation, there will be some oil on the inside of the leaf that is outside the joint between the oil ring and the bearing. The lubricating oil may be Throwing it out from here, the dust-proof label can also not get in the dust. Cooling fan manufacturers and companies can already make hydraulic bearing-type cooling fans for most of their products. This is just to target some large-volume customers and use automated production equipment to assemble them at a lower cost. Of course, we still make oily ones with a small amount, and the equipment debugging method is quicker and the cost is lower.
