The SI40AX375 features a space-saving design with dual cushioning adjustment screws for precise end-position control. Its anti-rotation rod design prevents unintended turning during operation. The cylinder tube undergoes multi-stage surface treatment including anodic oxidation and particle sealing for enhanced corrosion resistance.
- Carton sealing machinery - box compression
- Plastic injection molding - ejector mechanisms
- Conveyor systems - gate actuation
- Automated assembly lines - part positioning
- Textile machinery - tension control devices
Maintenance tip:
When used in vertical orientation, install an air dryer to prevent condensed water accumulation.
For high-cycle applications (>50% ED), reduce operating pressure by 20% to extend seal life.
