NANO Ceramic Bearing (NANO Ceramic Bearing, NCB) still in essence is a kind of oil Bearing, was first introduced by foxconn in their products. Traditional oil bearing SKF Bearing Series http://skf-bearings-lb.com/index.php/Index/aboutus/ fan in use process more serious wear and tear, and when used for a long time the reliability is low. Nano bearing effectively overcome the problem: ceramic bearing technology adopted special macromolecule material with special additives to fully mix, bearing the core we use special dioxide comprehensive materials, made use of punching die and sintering process, crystal particles by past 60 dropped to 0.3 um um, solid, smooth, wear-resisting and so on characteristics. Nano ceramic bearing has a strong ability of resistance to high temperature, less volatile, which greatly extend the service life of the fan, the nature of the nano bearing similar to ceramic, as it is smooth grinding. According to the test, using nanometer ceramic bearing of fan average service life of 150000 hours or more. The technology is not the real nano technology, the use of materials is not the real nanoscale materials, merely adopted nano words like to attract attention.
