HQW is able to fulfill particularly high requirements with spindle bearings in the hybrid version. The inner and outer ring are made of stainless steel, the balls of silicon nitride. Hybrid spindle bearings are indicated by “HYQ” in the HQW designation system. By using hybrid bearings, the speed limit can be increased by up to 50%, as can be seen in the figure below. In addition, you can achieve a significantly higher lifetime in areas where there is inadequate lubrication. Please do not hesitate to ask our application engineers to what extent the respective advantages will affect your application.

    Advantages of SV30

  • Longer lifetime in comparison to conventional materials.
  • Maximun corrosion resistance.
  • Improved mechanical properties due to vert fine structure.
  • Quiet running.
  • High temperature resistance of up to 300℃.
  • High chemical resistance.

    SV30 Applications
