Description

​​SiC Ceramic Bearing Balls Brief

​​SiC Ceramic Bearing Balls G5 Grade High Hardness​​

Silicon Carbide (SiC) Ceramic Balls are an advanced ceramic material renowned for their ​​exceptional hardness​​, ​​extremely high wear resistance​​, ​​outstanding chemical corrosion resistance​​, and ​​excellent thermal shock resistance​​. With a density of approximately ​​3.10-3.20 g/cm³​​, they are lighter than many metals, helping reduce component weight and inertia. These balls can be manufactured via processes like ​​pressureless sintering​​, offer a flexible size range from sub-millimeter to several centimeters, and can be precision-ground to ​​G5 grade or higher. Surface finish can be polished according to application needs to meet specific requirements for precision and friction characteristics.

SiC Ceramic Balls Characteristic

Characteristic Dimension​​

​​Core Advantage​​

​​Exceptional Hardness​​

Mohs hardness up to Grade 9​​, Vickers hardness (Hv) typically in the range of ​​2000-2500​​, its hardness is ​​second only to diamond​​.

​​Excellent Wear Resistance​​

Due to its ultra-high hardness, it can ​​significantly withstand wear in high-friction environments​​, ensuring an ​​exceptionally long service life​​.

​​High Thermal Stability​​

​​Melting point as high as ~2050°C​​, can maintain stable strength and hardness at ​​1600°C​​ or even higher temperatures, ​​strength remains almost unchanged at high temperatures​​.

​​Low Thermal Expansion Coefficient​​

Thermal expansion coefficient as low as ~​​4.5×10⁻⁶/K​​, making it ​​less prone to cracking or deformation​​ under drastic temperature changes, with excellent thermal shock resistance.

​​Outstanding Chemical Inertness​​

Exhibits excellent corrosion resistance to ​​most strong acids, strong alkalis​​, and salts, suitable for extreme chemical environments with ​​pH 1-14​​ (e.g., electroplating solutions, seawater desalination systems).

​​Lightweight​​

Density is approximately ​​3.10-3.20 g/cm³​​, ​​less than 40% of steel balls​​. This can significantly reduce the inertial load of high-speed rotating equipment, with an energy saving rate of ​​15%-20%​​.

​​Low Friction Coefficient​​

The friction coefficient is relatively low (approx. ​​0.02-0.1​​). Combined with its high hardness, it can reduce motion resistance, friction heat accumulation, and equipment temperature rise.

​​Electrical Insulation & Non-Magnetic​​

It is a good ​​electrical insulator​​ (resistivity >10¹² Ω·cm) and is ​​non-magnetic​​. This is crucial for avoiding interference with precision electromagnetic equipment.
