Metal Processing

Pinion stands, drive gears, and gearboxes for rolling mills and metal-processing lines under constant heat and tonnage.

Built for metal processing

Metal producers depend on gearing that holds up to extreme heat, heavy tonnage, and nonstop operation. We supply pinion stands, drive gears, and gearboxes for rolling mills, continuous casters, and furnace equipment — engineered for tight tooth control and long service life under punishing thermal and mechanical loads.

Challenges we solve

  • High-temperature, high-tonnage rolling environments
  • Tight lead and profile control for pinion stands
  • Matched double-helical sets for smooth, high-load meshing
  • Rapid turnaround to minimize line stoppages
