High-performance ISO-compliant pneumatic cylinder designed for heavy-duty industrial applications. Features precision-machined components with double-acting operation and corrosion-resistant construction. The adjustable cushioning mechanism minimizes impact noise and vibration at stroke ends, while the modular design allows easy integration with position sensors (magnetizable piston version available).
- Automated material handling systems
- Metal stamping press ejection mechanisms
- Packaging machine actuation
- Automotive assembly line tooling
- Foundry equipment operation
- Plastic injection molding machine components
Installation note:
Ensure proper alignment of piston rod axis with load direction. Use flexible couplings for
applications with lateral forces. For vertical installations, maintain 20% extra thrust capacity
margin. Lubricate through air supply (ISO VG32 recommended) if operating in high-cycle conditions.
