We follow ISO quality standards, ensuring that all SiC ceramic balls undergo high-temperature sintering and precise finishing. The balls are tested using optical microscopes and X-ray technologies to guarantee consistent quality and surface integrity. Every product meets strict industrial standards for performance and dimensional accuracy.
We offer OEM customization for specific sizes, performance, and processing requirements. Custom products undergo rigorous testing and quality control to ensure consistency and reliability.
What is a silicon carbide bearing ball?
Silicon carbide bearing balls are ultra-hard, highly durable balls designed for applications requiring low friction and high wear resistance. These balls offer superior performance compared to traditional steel or ceramic balls and can withstand extreme temperatures, making them ideal for high-temperature and high-pressure applications.
What are the advantages of using silicon carbide bearing balls?
SiC bearing balls are harder, lighter, and more wear-resistant than steel or ceramic balls. They are capable of operating in harsh conditions, with better thermal conductivity and a lower coefficient of friction, resulting in smoother, more efficient operation. They are also highly resistant to corrosion, making them perfect for applications in aggressive environments.
What are the recommended storage conditions for silicon carbide bearing balls?
Store SiC bearing balls in a cool, dry, and clean environment to prevent contamination or physical damage. Proper packaging should be maintained to protect the balls and ensure their dimensional integrity.
