About the Airtac SAI40 Standard Air Cylinder SAI40BX80
The AirTAC SAI40X80 is a double-acting ISO 15552 profile cylinder engineered to deliver 628 N of push force at 0.5 MPa and 879 N at 0.7 MPa. Its 80 mm stroke provides a compact extension distance perfectly suited for mid-range actuation tasks. As a genuine AirTAC component, it ensures reliable pneumatic performance.
Beyond the standard specifications, this specific unit is configured with a SUS304 stainless steel rod (material code B) for superior corrosion resistance in humid or mildly chemically washed environments. It utilizes PT tapered port threads, and because it lacks the -S magnet suffix, it operates without integrated position sensing.

Where the Airtac SAI40 Standard Air Cylinder SAI40BX80 Is Used
Clamping Mechanisms
Provides 628 N of push force at 0.5 MPa to securely hold medium-weight metal or composite parts during machining and assembly processes.
Package Diverting
The 80 mm stroke actuates diverter arms swiftly at speeds up to 800 mm/s to route small to medium parcels on packaging lines.
Material Ejection
Uses the 879 N push force at 0.7 MPa to positively eject molded components or stamped parts from machinery fixtures.
Is the Airtac SAI40 Standard Air Cylinder SAI40BX80 the Right Cylinder?
Select this 40 mm bore when an application requires stepping up from a 32 mm bore (which provides 402 N at 0.5 MPa) to handle heavier payloads, but a larger 50 mm bore (982 N at 0.5 MPa) would be physically oversized. The 80 mm stroke is optimal for short, rapid movements. If your mechanism requires holding a load vertically when air pressure is removed, note that the standard adjustable air cushions only decelerate the piston at stroke ends and do not function as a brake; you should specify the SAIL variant with an air-released lock or use an external pilot check valve.
For a seamless ISO 15552 direct replacement, match the 40 mm bore, 80 mm stroke, G1/4 port size, and your required mounting accessory (such as FA foot or TC trunnion). If sensor tracking is needed later, order the -S magnet option to utilize CMSE or DMSE switches in the dual barrel grooves.
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 SAI40 Standard Air Cylinder SAI40BX80 FAQ
The SAI40X80 generates a push force of 628 N at 0.5 MPa and 879 N at 0.7 MPa. The pull force is 528 N at 0.5 MPa.
Yes, the SAI40X80 is dimensionally interchangeable per ISO 15552. You can use it as a direct replacement for other ISO 15552 profile cylinders by matching the 40 mm bore, 80 mm stroke, and G1/4 port size.
