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.
Why NUODUN Was Selected
- High precision under heavy load—ideal for controlling roller pressure in glass forming
- Self-locking safety design preventing roller drop during power loss
- Long operational lifespan through hardened gears and optimized lubrication
- Modular configuration for multi-point lifting and synchronized motion
- Reliable performance in demanding industrial environments
Customer Benefits
- Improved sheet thickness uniformity and product quality
- Reduced downtime through durable, low-maintenance design
- Safer lifting operations with built-in self-locking
- Greater flexibility to process different glass thicknesses
- Enhanced overall equipment stability and longevity
