About the Airtac SAI80 Standard Air Cylinder SAI80BX5S
The AirTAC SAI80X5-S is a double-acting ISO 15552 profile cylinder engineered for short-stroke heavy-duty tasks. It provides a robust push force of 2513 N and a pull force of 2268 N at 0.5 MPa. The 5 mm stroke is tailored for high-force clamping, pressing, or ejection operations where minimal travel distance is required.
This specific configuration features a SUS304 stainless steel rod (material code B) for superior corrosion resistance. Equipped with a built-in magnet (-S), it seamlessly integrates with CMSE and DMSE sensor switches via the dual-side barrel grooves. Fluid ports utilize PT tapered threads, and the adjustable air cushions at both ends ensure smooth deceleration even at short distances.

Where the Airtac SAI80 Standard Air Cylinder SAI80BX5S Is Used
Heavy-Duty Stamping
Ideal for short-travel stamping and marking operations where the 2513 N push force at 0.5 MPa is sufficient to deform or secure heavy metal components.
Pallet Stopper
Acts as a high-strength stopper gate on heavy-duty conveyor lines, using the 5 mm stroke to halt pallets without requiring extensive cylinder footprint.
Clamping Fixture
Provides rigid clamping pressure for large workholding fixtures, utilizing the SUS304 rod to prevent corrosion in humid machining environments.
Is the Airtac SAI80 Standard Air Cylinder SAI80BX5S the Right Cylinder?
Selecting this 80 mm bore over the 63 mm variant significantly upgrades your force output, stepping up from 1559 N to 2513 N at 0.5 MPa. If your application requires even less travel or higher clamping density, the larger 100 mm bore offers 3927 N of push force. Because the stroke is only 5 mm, side-load stress on the rod bearing is inherently minimal, though ensuring pure axial load alignment remains critical for seal longevity.
For ISO 15552 direct compatibility, verify the 80 mm mounting dimensions, the 5 mm stroke requirement, and the PT G3/8 port size. Mounting accessories include LB foot brackets, FA/FB flanges, and TC trunnion options. Note that this standard SAI cylinder does not function as a dead-stop or safety lock; if pressure drops, the piston will drift. For position holding without live air pressure, specify the SAIL lock or BSAI clamp-lock variant.
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 SAI80 Standard Air Cylinder SAI80BX5S FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder generates 2513 N of push force and 2268 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 513 kgf of theoretical force.
Yes. The SAI series is dimensionally interchangeable per ISO 15552 standards. You can drop it into existing 80 mm bore ISO 15552 mounting interfaces using the PT G3/8 port and standard mounting accessories.
