About the Airtac SAI80 Standard Air Cylinder SAI80AX550S
The AirTAC SAI80X550-S is a double-acting ISO 15552 profile cylinder featuring an 80mm bore and a 550mm stroke. It generates 2513N of push force and 2268N of pull force at 0.5 MPa, making it well-suited for heavy-duty positioning tasks requiring substantial travel distance.
This specific configuration includes a SUS420J2 stainless steel rod for enhanced corrosion resistance and a built-in magnet (-S) that enables direct mounting of CMSE or DMSE sensor switches along the dual grooves on the extruded aluminum barrel. It utilizes PT tapered thread ports sized at G3/8.

Where the Airtac SAI80 Standard Air Cylinder SAI80AX550S Is Used
Automated Pressing
Provides consistent 2513N pressing force for assembling heavy mechanical components over a 550mm travel range.
Material Diverting
Actuates large lane diverter arms on packaging lines, utilizing the magnet-equipped stroke sensing for precise timing.
Long-Stroke Ejection
Ejects finished molded parts from large injection molding machines, relying on the durable SUS420J2 rod.
Is the Airtac SAI80 Standard Air Cylinder SAI80AX550S the Right Cylinder?
This 80mm bore provides 2513N at 0.5 MPa; step down to a 63mm bore if your application only requires 1559N, or move up to a 100mm bore for 3927N. At 550mm of stroke, the unsupported rod is highly susceptible to bending under side loads. Implement an external guide rail or select a guided cylinder to prevent rod-bearing damage.
The adjustable air cushions at both ends decelerate the piston near stroke end but do not lock the load. If the machinery loses air pressure, the rod will drift; use the SAIL locking variant or an external pilot-operated check valve for fail-safe position holding. For ISO 15552 direct replacements, match the 80mm bore, 550mm stroke, G3/8 PT port, and appropriate FA or TC mounting accessories.
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.
