100pcs SIC Ceramic Balls 2.0mm/2.381mm/2.5mm/2.778mm Silicon Carbide Precision Bearing Ball Miniature(100pcs 2.778mm)

Applications‌: widely used in bearings, industrial machinery, mining equipment, and automotive hubs.(1) The upper limit of use temperature is high, and the high-temperature strength of silicon carbide is high. When the temperature exceeds 1200°C, the strength of SiC begins to exceed the strength of Si3O4;(2) Thermal conductivity is the highest, about 150W/m.k, during the operation of the bearing, the heat can be quickly dissipated;(3) It has the best thermal shock resistance and can be considered for use in situations where the temperature changes rapidly;(4) The thermal expansion coefficient is low (only larger than silicon nitride) and can maintain good dimensional accuracy in high temperature environments;(5) The elastic modulus is the highest, which improves the dynamic stiffness of the bearing and can be used in situations with high stiffness requirements;(6) The lowest density, which can reduce centrifugal load and friction, and is used in high-speed environments;(7) Can be used in petroleum, chemical industry, machinery and other fields.High-precision grades for metrology.
