The SI63X125TC industrial cylinder delivers 4.9 cm³ displacement per millimeter stroke, optimized for medium-duty linear motion. Features corrosion-resistant anodized surfaces and precision honed bore (Ra≤0.4μm). Requires ISO 8573-1:2010 Class 3-4-3 compressed air. Includes magnetic piston for sensor compatibility (sensors sold separately).
- Automated packaging machine clamp positioning
- Plastic injection molding ejector systems
- CNC machine tool chip conveyor gates
- Automotive welding fixture actuation
- Printing press roller engagement mechanisms
Installation guidelines:
Maximum side load 15% of theoretical thrust. For vertical mounting,
use counterbalance valves. Maintain 0.3-1.0 m/s piston speed for
optimal seal life. Align mounting surfaces within 0.2mm/m tolerance.
