The SI50X1340S is a heavy-duty long-stroke pneumatic cylinder optimized for high-momentum applications. Its reinforced rod bearing design minimizes deflection during extended stroke operation, while the double O-ring piston seal ensures leak-free performance even under side load conditions. The cylinder features a wear-resistant aluminum alloy barrel with hard anodized coating for extended service life.

Installation note:
For strokes exceeding 1000mm, use intermediate rod supports (optional ASQ series) to prevent buckling.
Maintain 0.5–1.0mm alignment tolerance per meter during mounting. Lubricate rod weekly with ISO VG32 hydraulic oil
in high-cycle applications (>500,000 cycles/month).
