High-force industrial cylinder engineered for heavy payload applications requiring extended stroke precision. Features oversized piston seals for minimal internal leakage (≤3 cm³/min at 0.5MPa) and chromium-plated piston rod (Ø35mm) with integrated scraper for contamination resistance. Requires 40μm filtered air and periodic lubrication (every 2000km stroke) for optimal performance.
- Automotive assembly line clamping systems
- Steel coil handling in rolling mills
- Injection molding machine ejectors
- Shipbuilding plate positioning systems
- Hydraulic press force amplification
Installation note:
Requires rigid mounting structure (≥200N·m torque for M16 bolts).
Maintain 0.5° maximum angular misalignment during installation.
Cycle rate should not exceed 80% of calculated maximum (based on Cv value 2.8).
