- Steel mill rolling equipment positioning
- Injection molding machine ejector mechanisms
- Warehouse automated pallet stacking systems
- Paper mill roller gap adjustment units
Installation guidelines:
Allow minimum 50mm clearance around cylinder body for heat dissipation.
Align piston rod within 0.2mm perpendicular tolerance. Lubricate through
air supply (oil-fog lubrication at 1-2 drops/m³) or manual greasing every
3,000km of cumulative stroke movement.
