220V Cooling Fan of durability

1, "220V Cooling Fan" high speed and acceleration - dn values can operate under conditions of more than 3 million, and the skid, wear and heat can be reduced;
2,12V DC fan long life, resistance to wear - full ceramic bearing fatigue life expected 10-50 times longer than steel bearings, hybrid ceramic bearings, life expectancy is higher than steel bearing life is about 3-5 times;
3, "220V Cooling Fan" minimal lubrication required - a low friction coefficient of the ceramic material, ceramic bearings lubricated by oil, the lubricating oil in the case of thinning or lean, its lubricating ability is still lower than the conventional steel bearings traditional lubricants;
4, abrasion - Since the ceramic material is inert material, it is more resistant to corrosion and wear;
5, rigidity - due to the elastic modulus of the ceramic material is high, its rigidity than ordinary steel bearings Large 15-20%;
