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! u003cbru003e u003cbru003e u003cbru003e 　　1) Oil bearing u003cbru003e u003cbru003e u003cbru003e 　　The manufacturer of miniature waterproof car cooling fan tells you that the accuracy of oil-impregnated bearings is low; the service life is about 20,000 hours, total: 834 days, 2.3 years; the bearing is in contact with the shaft relative motion line; the running friction is relatively large; u003cbru003e u003cbru003e u003cbru003e The manufacturer of 　　 miniature waterproof car cooling fan tells you that you can store oil in the oil hole on the inner diameter surface of the bearing by vacuum impregnation, and form an oil film lubrication by running friction and heat; u003cbru003e u003cbru003e u003cbru003e 　　 It’s better to use the fan vertically and fixedly. u003cbru003e u003cbru003e u003cbru003e u003cbru003e u003cbru003e u003cbru003e 　　2) Single ball bearing u003cbru003e u003cbru003e u003cbru003e 　　 miniature waterproof car cooling fan manufacturer tells you that the accuracy of single ball bearing is the second; the service life is about 30,000 hours, total: 1250 days, 3.4 years; both line and point contact; running friction second; u003cbru003e u003cbru003e u003cbru003e 　　 The manufacturer of the miniature waterproof car cooling fan tells you that this method of use has the characteristics of oil bearing/double ball bearing. The operating load mainly falls on the front ball, while the copper on the back provides the fulcrum function and functions according to the ball positioning. Heart adjustment; u003cbru003e u003cbru003e u003cbru003e 　　 It is better to use a vertical fixed fan. u003cbru003e u003cbru003e u003cbru003e u003cbru003e u003cbru003e u003cbru003e 　　3) Double ball bearing u003cbru003e u003cbru003e u003cbru003e 　　 miniature waterproof car cooling fan manufacturers tell you that double ball bearings have the highest accuracy; the service life is about 50,000 hours, total: 2084 days, 5.7 years; the relative movement of the bearing and the shaft is point contact; the movement friction is small; u003cbru003e u003cbru003e u003cbru003e 　　The internal ball of the bearing is positioned in the retainer with lubricating grease for rotation; u003cbru003e u003cbru003e u003cbru003e 　　 The fan can be fixed in any direction. u003cbru003e u003cbru003e u003cbru003e u003cbru003e u003cbru003e u003cbru003e 　　 The above introduction is a brief introduction to the cooling fan bearings of the miniature waterproof car cooling fan manufacturer. It is not necessary for most people to understand the principles that are too detailed. The points mentioned above are enough for general users. More information will increase the problem of choice.
