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.
