Heavy-duty long-stroke cylinder engineered for high load applications requiring precise linear motion. Features reinforced rod bearings for minimized deflection in extended stroke operations. The STC mounting configuration provides dual-position stability for vertical/horizontal installations. Requires ISO 8573-1 Class 3 lubricated or non-lubricated air.
- Automotive press line material handling
- Injection molding machine ejector systems
- Steel coil handling equipment
- Large-scale packaging machinery
- Paper mill roller positioning
Installation guidelines:
For strokes >1000mm, use intermediate support brackets every 800mm.
Maintain 0.5-1mm/m alignment tolerance. Lubricate rod weekly in high-cycle
applications (≥500 cycles/day). Avoid side loads exceeding 150N.
