A high-rigidity ISO-standard pneumatic cylinder featuring wear-resistant chromium plating and precision honed tube. The SAI63X125 combines medium-bore force output with optimized stroke length for repetitive linear motion tasks. Built-in magnetic piston allows for position sensing compatibility. Requires 40μm filtered compressed air with 1-50 mg/m³ lubrication (ISO 8573-1 class 4-4-3).
- Plastic injection molding machine ejectors
- Automated assembly line clamping units
- Packaging machine pusher mechanisms
- Textile machinery tension control systems
- Automotive welding fixture positioning
Installation tip:
For vertical mounting, use reinforced rod-end support brackets.
Lubricate through air supply for first 500km of stroke travel.
Allow 20mm clearance around cylinder for heat dissipation.
