The manufacturer of the miniature waterproof car cooling fan tells you the difference between the three types of car cooling fan bearings is
Mini waterproof car cooling fan manufacturers tell you that there are different types of cooling fans on the bearings. AC fans are generally oil-containing, single-ball, double-ball, and DC car cooling fans. On the basis of these three types, there are hydraulic and magnetic levitation. , Fluid dynamics, nano-ceramics, and some two types of hybrid bearings. The editor of the miniature waterproof car cooling fan manufacturer will briefly and intuitively introduce the difference in life and performance of oil, single ball, and double ball. In the following system, the manufacturers of miniature waterproof car cooling fans explain what are the advantages of these three types, hoping to help users make preliminary judgments according to their needs, and select the right type of bearings. Let us take a look!
