  • These guides for high performances for fairly aggressive yarns.
  • Paritcular components for the formation of textile yarns, as for instance :
    • Ceramic navels, mirror polished for open End spinning machines.
    • Compressed air intermingling inserts.
    • Friction discs, guide discs, knife disc for texturizing machine and thread guides for oil application.
  • Component for pumps and valves, such seal rings, pistons, sleeve bearings, shaft cover sleeves, shafts inpellers, seal plates for any kind of liquid, bolls for ball valves etc.
  • Seal disc for mixing taps.
  • Armour-plates, nozzles of different types.
  • Insulating pieces for electrical and electronic fields etc.
  • Ceramic cavities for laser sources.
RX - 1Aluminium Oxide Toughened with Zirconium Oxide AI2O3-ZrO3Thread guides with low friction coefficient and good wear resistance for very special delicate yarns.-

Zirconium Oxide ZrO3
Stabilized with yttrium oxide Y2O3
Stabilized with magnesium oxide MgO
Stabilized with magnesium oxide MgO + Calcium Ozide CaO
