1. Material: AL2O3, ZRO2, SI3N4
2. Size: 1 mm-50.8mm, or as per clients' requirements
3. Color: White, black, etc.
4. Feature: Ceramic balls are self-lubricating, so it's both OK to use grease or not use. It is of low density, medium elasticity, small thermal expansion, high hardness, high temperature resistance, good corrosion resistance, magnetism free. Ceramic ball bearings using silicon nitride ceramic balls as rolling element, can obviously improve bearings' using life, and extremely expande bearings' application field.
5. Application: High precision and high rotating speed machine tool, automobile, racing car, metro, power generator, aerospace generator, petrol and chemical machine, metallurgy machine.
6. Packing: Industrial packing, or as clients' requirement.
