NUODUN Screw Jacks in Glass Calendering Line

Glass calendering (glass rolling) lines require highly stable, precise vertical-positioning systems to control roller gaps, regulate pressure, and ensure uniform sheet thickness during hot-end forming. NUODUN supplied heavy-duty screw jacks engineered to operate reliably under high temperature, continuous load, and demanding alignment conditions.

Application

The pictured system integrates multiple NUODUN worm-gear screw jacks, mounted vertically to support and adjust upper calender rollers. These lifting units enable controlled movement with high repeatability, allowing operators to finely tune the roller gap for different glass thickness and processing requirements.

Functions Enabled by NUODUN Screw Jacks

• Precise roller gap adjustment
  Micron-level lifting control ensures consistent glass thickness across the full sheet width.
• High load capacity & structural rigidity
  Designed to carry significant vertical loads generated during calendering and compression.
• Smooth, stable lifting under continuous duty
  Worm-gear mechanisms deliver self-locking capability, preventing unintended downward movement.
• Temperature-resistant performance
  Materials and lubrication optimized for elevated ambient temperatures near hot glass sections.
• Easy integration into multi-jack systems
  Supports mechanical or motor-driven synchronization for long-span calendering equipment.
