silicon nitride ceramic ring vs porous ring uses

  • Full Ceramic and Ceramic Hybrid Bearings by Boca

    Ceramic is non-porous, non-magnetic, non corrosive and lighter than steel. In ball form, ceramic balls are also harder than steel and because ceramic balls are non-porous they are virtually frictionless and capable of spinning faster than steel balls. Ceramic Balls are usually made of following materials: Silicon Nitride (SiN4) Alumina Oxide ...
