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.

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.
