The SI40X775STC long-stroke pneumatic cylinder combines high rigidity and precise linear motion control. Features dual anti-rotation grooves (180° apart) for stable load guidance and a wear-resistant chromium-plated rod surface with 4μm Ra roughness. Optimized air consumption design reduces compressed air usage by 15% compared to previous models.
- Palletizing robot arm extensions
- Automated foundry mold clamping systems
- Large-format CNC machine tool doors
- Solar panel production line positioning
- Automotive assembly line conveyor stoppers
Installation guidelines:
Maximum side load ≤35N. For horizontal mounting exceeding 500mm stroke,
use dual guide rails with ≤0.15mm/m alignment tolerance. Lubricator required
if air line contains particulate >5μm. Cycle rate should not exceed 85% of
calculated maximum (≤3,200 cycles/hour at full stroke).
