hybrid ceramic ball bearings in sizes 5X10X4mm, 5x13x4mm and 10x15x4mm with an abec grade of 9 or higher. 

Ceramic ball bearing feature :

(1) High-speed bearing: cold resistance, small elasticity, high pressure resistance, poor thermal conductivity, light weight, friction coefficient
(2) High temperature resistant bearing: the material itself has a high temperature resistance of 1200 ° C, and self-lubricating
(3)Corrosion-resistant bearings: the material itself has corrosion resistance
(4) Anti-magnetic bearing: no magnetic, so it does not absorb dust
(5) Electrically insulating bearings: due to high resistivity
(6) Vacuum bearing: oil-free self-lubricating property due to ceramic materials

Ceramic ball bearings can be used for:  Bicycle, Medical equipment, optical instruments, printing machinery, machine tools, high-speed motor, low temperature engineering, food processing machinery,aerospace, marine, nuclear industry, petroleum, chemical, textile industry, machinery, metallurgy, electric power
