8x16x5mm ZrO2 Ceramic Bearing 688CE Full Ceramic Ball Bearing for Fidget Hand Spinner

1.  Because of the unique ceramic materials, vacuum oil-free self-lubricating property, in ultra-high vacuum environment, zirconia ceramic bearings can overcome the plain bearing can not realize the problems of lubrication.

2.  With corrosion resistance, cold resistance, stress resistance to pressure, small elastic, thermal conductivity, light weight, the advantages of small friction coefficient.

 

Applications:Fidget hand spinner, bicycle, medical equipment, optical instruments, printing machinery, machine tools, high-speed motor, low temperature engineering, food processing machinery.

Note:Because of the full ceramic bearing,its turning time will not last long until you use it a period of time and it don't need to add lubricating oil.
The actual turning time depends the structure of your spinner and your proficiency.
