zirconium vs silicon nitride ceramic ring in austria

  • Ceramic bearings: zirconia or silicon nitride? |

    2020-3-6 · Ceramic bearings made from ZrO 2, or zirconium dioxide, is a tough ceramic material with very similar expansion properties to steel, although they are 30% lighter. This is an advantage when considering shaft and housing fits for higher temperature applications, where bearing expansion could mean the shaft no longer fits.
