- Foundry equipment for mold clamping
- Paper converting machinery with long-stroke requirements
- Heavy-duty lifting platforms in logistics centers
- Steel coil handling in metal processing lines
 Installation advice: 
            Maintain 0.5-1mm/m alignment tolerance during mounting. For vertical installations, 
            use auxiliary rod support when stroke exceeds 500mm. Lubricate through air supply 
            (ISO VG32 turbine oil recommended).
