High-quality ceramic rolling elements have very high requirements on the performance or indicators of the ceramic itself (such as flexural strength, fracture toughness, hardness, microstructure, Weibull modulus, etc.) and precision processing capabilities. Especially in the field of silicon nitride ceramic balls, on the one hand, even if the ceramics with different properties are processed into products of the same accuracy level, the fatigue life may be tens to hundreds of times worse. On the other hand, the application side requires the surface processing quality of ceramic balls. Also very strict. Since its establishment, Jinsheng Ceramics has been focusing on the research and development of ceramic materials and precision processing technology, as well as the continuous improvement of quality management capabilities. After more than ten years of continuous efforts, it has developed different materials, multiple levels of ceramic materials and corresponding ceramics Sperm ball.
