1, "220V AC Cooling Fan" high speed and acceleration - dn value can operate under conditions of over 3 million, and the slip, abrasion and heat can be reduced;
2, "220V AC Cooling Fan" DC fan long life, resistance to wear - full ceramic bearing fatigue life expected 10-50 times longer than steel bearings, hybrid ceramic bearings, steel bearing life than the life of a high 3 -5 times around;
3, the required minimal lubrication - 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 commonly used conventional steel bearing lubricant;
4, abrasion - because the ceramic material is inert material, it is more resistant to corrosion and wear;
5, rigidity - by the elastic modulus of the ceramic material is high, its larger rigidity than the ordinary steel bearing 15-20%;
6, "220V AC Cooling Fan" temperature - Full ceramic bearings can operate in temperatures above 500 ℃;
7, torque low - according to the structure, ceramic bearings reduce torque about one-third;
8, non-magnetic non-conductive - ceramic bearings can not be magnetic, electrical damage.
