[Automotive AC fan] High dang bearing casts a good fan

The bearing of the automobile AC fan is a relatively high-dang bearing. It adopts the form of rolling friction and adopts two ball bearings. There are several tiny steel balls around the axis in the bearing. When the fan or the axis rotates, the steel balls rotate with it. Because they are all spheres, the friction is small and there is no problem of oil leakage. The advantages of automotive AC fan bearings are long life, about 50000-100000 hours; good anti-aging performance, suitable for fans with higher speeds. Automotive bearings and hydraulic bearings have better sealing properties, especially automotive bearings. The automobile bearing is completely embedded in the fan, and the rotating part is not in direct contact with the outside world. In a sealed environment, the working environment of the bearing is relatively stable. Therefore, almost all large-caliber automotive AC fans of the 5000 rpm class use automotive bearings. u003cbru003e u003cbru003eFriendly link: Mini DC fan manufacturer http:///products-detail.asp?cpidu003d125 u003cbru003eFriendly link: Cooling AC fan http:///products-detail.asp?cpidu003d71
