A heavy-duty ISO-compliant pneumatic cylinder optimized for high-force linear motion. Features precision-machined components with triple sealing system (rod seal, buffer seal, and wiper) for extended service life. The corrosion-resistant construction and reinforced rod bearing make it suitable for 24/7 operation in harsh environments. Requires 40µm filtered air with ISO VG32 lubrication recommended.
- Automotive production line clamping fixtures
- Steel mill material handling systems
- Injection molding machine ejectors
- Paper processing equipment actuators
- Construction machinery hydraulic assist systems
Installation note:
Ensure proper rod alignment (max 0.2° angular misalignment) and use
vibration-damping mounts in high-cycle applications (>500,000 cycles/year).
Lubricate through air supply at 1-2 drops/m³ for optimal performance.
