13.494mm High-temperature Resistant Silicon Nitride (Si3N4) Ceramic Balls
⚙️product description:
Material: The main component of the 13.494mm ceramic ball is silicon nitride. This is a new type of inorganic non-metallic material, which is formed by high-temperature sintering in a non-oxidizing atmosphere.
Specification: The diameter is 13.494mm, and it belongs to a medium-sized ceramic ball. This specification is commonly used in many mechanical components that require high precision and specific performance.
Color: It is usually black or gray, and the specific color depends on its production process and the added trace elements.
Accuracy level: The precision level of silicon nitride ceramic balls can reach a relatively high level, such as the G5 grade, etc. High-precision ceramic balls have strict control over aspects such as dimensional tolerance, roundness, and surface roughness, and can meet the usage requirements of precision machinery.
⚙️Performance features:
High Strength: The bending strength can reach over 500 MPa, capable of withstanding significant external forces, and is unlikely to rupture. It is suitable for applications with high strength requirements.
High Hardness: The Mohs hardness can reach 9, which is more than twice that of bearing steel, featuring excellent wear resistance with an extremely low wear rate.
High Temperature Resistance: It can operate stably at temperatures below 1200°C, and can withstand instantaneous high temperatures up to 1500°C. It still maintains excellent performance in high-temperature environments.
Corrosion Resistance: It has excellent anti-corrosion properties, resistant to acids and alkalis, and can be used in seawater for long-term use, suitable for various harsh chemical environments.
Low Density: The density is approximately 3.2 g/cm³, which is nearly 1/3 of that of bearing steel, resulting in a light weight and low centrifugal force during rotation, enabling high-speed operation.
Good Insulation: It has excellent electrical insulation properties, with a resistivity greater than 10¹² Ω·cm, and can be used in electrical insulation components.

⚙️Precautions:
| 1. Keep clean |
2. Use with caution |
3. appropriate tool |
4. Hot-loading |
5. Be careful of rust |
| Dust will have a bad effect on the bearing, so keep the surrounding clean. |
Strong impact during use can easily cause scratches and indentations. |
Avoid replacing existing tools, and use appropriate tools. |
Bearings are precision parts, so hot installation is recommended. |
Sweat on your hands during operation will cause rust, so it is best to wear gloves. |
