A heavy-duty ISO-compliant pneumatic cylinder optimized for long-stroke industrial applications. Features double-acting operation with corrosion-resistant construction and precision honed tube for smooth linear motion. The 40mm bore size delivers balanced force-to-size ratio, making it ideal for medium-load pushing/pulling tasks. Includes magnetic piston for sensor compatibility.
- Assembly line material handling systems
- Automated palletizing equipment
- Plastic injection molding ejectors
- Automotive welding fixture positioning
- Paper feed mechanisms in printing presses
Installation guidance:
Maintain proper alignment with guided rails in long-stroke applications.
For vertical mounting, consider adding a mechanical brake lock.
Lubricate through air supply (ISO VG32) if operating below 0.3 MPa.
