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.

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.
