About the Airtac SAI80 Standard Air Cylinder SAI80X45S
The AirTAC SAI80X45-S is a double-acting ISO 15552 profile cylinder offering a robust push force of 2513 N at 0.5 MPa. Its 45 mm stroke is ideal for short, high-force clamping or ejection tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that is dimensionally interchangeable with other ISO 15552 profile cylinders.
This specific configuration includes a magnet (-S) for direct mounting of CMSE or DMSE sensor switches along the dual side grooves. It uses standard carbon steel for the piston rod and features PT tapered port threads, ensuring a reliable, leak-free connection in demanding pneumatic setups.

Where the Airtac SAI80 Standard Air Cylinder SAI80X45S Is Used
Heavy-Duty Clamping
Secures large metal or composite workpieces during CNC machining, utilizing the 2513 N push force to prevent part shifting under high cutting loads.
Product Diverting
Actuates a heavy diverter arm on a packaging line, using the short 45 mm stroke to quickly push dense cartons onto a secondary track.
Stamping Press Ejection
Ejects thick stamped metal blanks from a die, relying on the robust carbon steel rod to absorb initial impact without bending.
Is the Airtac SAI80 Standard Air Cylinder SAI80X45S the Right Cylinder?
Choose this 80 mm bore when a 63 mm cylinder (providing 1559 N at 0.5 MPa) lacks the necessary thrust for your heavier payloads. The short 45 mm stroke keeps the rod fully supported within the bearing, minimizing rod deflection. If your machinery requires the load to remain held during a complete loss of air pressure, note that the standard adjustable air cushions only decelerate the piston at end-of-stroke; you must integrate an external pilot-operated check valve or select the SAIL locking variant for true drop prevention. Replacement drop-in units must match the 80 mm bore, 45 mm stroke, G3/8 port, and the -S magnet option.
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.
