There are many sizes of balls.
(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.
The surface is smooth and polished, which reduces friction and noise during operation.
