The biggest difference between nano-ceramic bearings and general-purpose fan bearings is the selection of ceramic bearings made of nano-sized zirconia powder as the main material and matched with special nano-scale particle lubricants.
Nano-sized zirconia powder has the characteristics of greatly decreasing sintering temperature, high hardness and high strength. The parameters in terms of thermal expansion coefficient, friction coefficient, density and hardness are much higher than those of oil seal bearings and ball bearings. Bearing steel; even some parameters have reached the level comparable to the diamond coefficient. Using these features makes the nano-ceramic bearing itself able to achieve a very high density.

The traditional oil-sealed bearing fan is severely worn during the operation; the service life is very short; and the temperature rise is very simple, so that the internal heat is swollen and the axis is stuck; the fan speed is reduced or even the transition is stopped; This is extremely risky for the chip of the device. The fan with nano-ceramic bearing has a very high temperature resistance; and the nano-sized particle lubricant has the characteristics of not easy to evaporate; the fan life of the nano-ceramic bearing is selected. The number is extended by several times.
According to the test; the average life of the fan using nano-ceramic bearings is more than 150,000 h; and the appearance of the temperature is too high and the axis is completely eliminated.
Compared with the ball bearing fan; the noise of the nano-ceramic bearing fan is also well controlled; the noise generated is 23 dB lower than the double ball bearing.
The nano-ceramic bearing fan is in the assembly process; it is also much simpler than the ball bearing fan; thus, the quality is also improved in the invisible; the cost is reduced.
Because the size of the nano-ceramic bearing is better than that of the 诜缟鹊 杓 杓 憧 憧 さ缁 さ缁 さ缁 さ缁 撸 撸 撸 撸 撸 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对 相对婊辉龃罅丝魍魍.
In the environmental test of nano-bearing fans repeatedly, nano-ceramic bearing fans have excellent functions in high temperature resistance, cold resistance, humidity and impact resistance. In the ambient temperature of 80 ° C and minus 30 C; after 246 h of continuous operation There is no abnormality in the fan. All the test samples passed the 480h test at a temperature of 40 ° C and 90% to 95% humidity.
