Characteristics of silicon carbide ceramic ball:
(1) The upper limit temperature is the highest, and the high temperature strength of silicon carbide is high. When the temperature exceeds 1200 ℃, the strength of SiC begins to exceed that of Si3N4;
(2) The highest thermal conductivity is about 150W / M? K, which can quickly dissipate heat during bearing operation;
(3) The thermal shock resistance is the best, which can be considered for the occasion of rapid temperature change;
(4) The coefficient of thermal expansion is low (only greater than Si3N4), which can maintain good dimensional accuracy in high temperature environment;
(5) The highest elastic modulus is about 420gpa, which improves the dynamic stiffness of the bearing and can be used in occasions requiring high stiffness, such as machine tool spindle;
(6) The lowest density can reduce centrifugal load and friction, and can be used in high-speed operation environment;
(7) It has the best corrosion resistance and can resist the corrosion of concentrated acid and alkali, especially HF.
