About the Airtac SAI50 Standard Cylinder SAI50AX80
The AirTAC SAI50X80 is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its 80 mm stroke provides quick, precise linear motion for mid-range automation tasks. As a genuine AirTAC component, it guarantees reliable performance in demanding environments.
This specific configuration features a SUS420J2 stainless steel piston rod for superior corrosion resistance and mechanical strength. The pneumatic supply connects via a tapered PT port, ensuring a secure, leak-free fitting. The extruded aluminum barrel design omits tie-rods, presenting a clean exterior that integrates seamlessly into modern machinery.

Where the Airtac SAI50 Standard Cylinder SAI50AX80 Is Used
Automated Clamping
Provides 982 N of thrust at 0.5 MPa to securely hold medium-weight workpieces during machining or assembly operations.
Product Diverting
The 80 mm stroke actuates diverter arms swiftly on packaging lines to route boxes without slowing throughput.
Vertical Lifting
Raises lightweight pallets or tote bins in material handling stations, utilizing the full 825 N pull force.
Is the Airtac SAI50 Standard Cylinder SAI50AX80 the Right Cylinder?
Choose this 50 mm bore when an application requires more thrust than the 40 mm bore (628 N at 0.5 MPa) provides, but you want to avoid the larger footprint of the 63 mm bore (1559 N at 0.5 MPa). The 80 mm stroke is optimal for short-travel clamping and lifting duties.
Because this is a double-acting cylinder, air pressure is required to both extend and retract the rod. If your system loses air pressure or the control valve is centered, the piston will drift and cannot hold a load. For fail-safe position holding, consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock cylinder. For direct replacements, match the 50 mm bore, 80 mm stroke, PT port thread, and appropriate mounting accessories like FA flanges or TC trunnions.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAI50 Standard Cylinder SAI50AX80 FAQ
