A high-rigidity ISO cylinder with optimized air consumption, featuring chromium-plated piston rod for enhanced corrosion resistance. The SI40 series utilizes precision honed tubing for smooth operation, with integrated magnet slots for sensor compatibility. Requires filtered air with 5-40μm filtration and ISO VG32 hydraulic oil lubrication if used in non-lubricated systems.
- Automated material handling systems
- Plastic injection molding ejectors
- Textile machinery tension control
- Automotive assembly line fixtures
- Printing press paper feed mechanisms
Installation note:
Ensure proper rod alignment (max 0.2mm lateral deviation) and use flexible couplings for stroke-end shock absorption. For vertical mounting, consider adding a guide mechanism for loads exceeding 5kg.
