Ceramic (Si3n4) Ball For Precision Bearing
Dalian Chengyi Mechanical Co., Ltd supplies silicon nitride (Si3N4) ceramic balls engineered for precision bearings, offering a density of 3.20 g/cm³. These balls are approximately 25 percent lighter than standard steel balls, reducing centrifugal force during high-speed rotation. They are widely used in aerospace, automotive, semiconductor equipment, vacuum pumps, medical devices and chemical processing due to their corrosion resistance, thermal stability and electrical insulation properties.
The silicon nitride ceramic balls are sintered at high temperatures in a non-oxidising atmosphere, achieving high strength, wear resistance and durability. They maintain their mechanical properties at temperatures up to 800°C, with almost no degradation in strength or hardness. The material’s self-lubricating properties allow it to operate in environments where traditional lubricants are incompatible or undesirable, such as vacuum or chemically aggressive conditions.
These ceramic balls are sourced for applications requiring high precision, low weight and resistance to harsh environments. Buyers typically confirm dimensional tolerances, surface finish and batch consistency for large orders. The supplier can provide custom specifications, and buyers should verify lead times for bulk shipments from Dalian, China.
