Silicon Nitride Ceramic

Home

Silicon nitride (Si₃N₄) is a high-performance structural ceramic with excellent properties such as high strength, high hardness, high temperature resistance, wear resistance, and corrosion resistance. Its density is only 3.2 g/cm³, its hardness exceeds 1500 HV, it can operate stably at 1200°C, has a low coefficient of thermal expansion, and excellent thermal shock resistance. It is widely used in bearing balls, cutting tools, engine components, aerospace, and other fields, making it an ideal alternative to metallic materials.

High Abrasion Resistance Skateboard Ceramic Bearings
Silicon Nitride Si₃N₄ Ceramic Bearings are high-performance core components in modern skateboarding equipment. Thanks to their superior physicochemical properties, they are gradually replacing traditional steel bearings and becoming the preferred choice for professional skateboarders and racing enthusiasts. Skateboard Bearings typically use the 608 specification (8mm inner diameter × 22mm outer diameter × 7mm width), which is the international standard size for wheeled sports equipment such as skateboards, inline skates, and roller skates.
