Silicon nitride ball
Widely used in fields with stringent material performance requirements, such as high-speed machine tool spindles, aerospace engines, and new-energy vehicles. The conventional range of 0.4–63.5 mm is suitable for precision mechanical components like bearings, valves, and pumps, offering high strength, wear resistance, and high-temperature tolerance. The 1.588–50 mm range meets the demands of complex manufacturing processes, including high-precision bearings and specialized equipment. The 3.02–20 mm range is employed in grinding processes, such as surface treatment of electronic components.

Detailed introduction
Product description:
Material: Silicon nitride
Diameter: 0.2 mm – 80 mm;
Accuracy class: G3, G5
Hardness: HV1600-1800
Features:
Corrosion Resistance: The Si-N covalent bond structure endows it with resistance to corrosion by acids, bases, and seawater, making it suitable for applications in the chemical, medical, and other industries. Self-Lubricating Properties: It can operate without the need for lubricants, making it ideal for environments with high levels of contamination or where adding lubricants is impractical.
Fatigue Resistance: High elastic modulus (44% higher than steel) and low thermal expansion coefficient extend bearing life and reduce deformation.
Applications: Widely used in fields with stringent material performance requirements, such as high-speed machine tool spindles, aerospace engines, and new-energy vehicles. The standard range of 0.4–63.5 mm is suitable for precision mechanical components like bearings, valves, and pumps, offering high strength, wear resistance, and high-temperature tolerance. The 1.588–50 mm range meets the demands of complex manufacturing processes, including high-precision bearings and specialized equipment. The 3.02–20 mm range is employed in grinding processes, such as surface treatment of electronic components.
Physical properties:
High hardness and wear resistance: The hardness can reach over HV1480, with excellent wear resistance, making it commonly used in precision components such as bearings.
Low density: With a density of 3.20 g/cm³, it is 59% lower than that of steel, reducing centrifugal force during high-speed operation.
High-temperature stability: Exhibits stable performance at 800℃ and can withstand temperatures exceeding 1200℃.
Magnetic properties: Non-magnetic and non-magnetic—possesses both insulating and magnetic properties, making it suitable for applications requiring electrical isolation.
