NINE STAR Hybrid Ceramic Ball bearings

  For especially problematic applications, NINE STAR offers Hybrid Ceramic Ball bearings. Using conventional
steel inner and outer rings, zirconium oxide (ZrO2) or silicon nitride (Si3N4) rolling elements provide excellent
electrical insulation while reducing rotating mass and improving heat dissipation.

The unique properties of ceramic rolling elements can also extend service life and extend grease intervals. Hybrid
Ceramic Ball bearings are gaining popularity in the wind energy industry, where the service access is difficult and conditions
especially harsh.
