About the Airtac SAI40 Standard Air Cylinder SAI40AX75
The AirTAC SAI40X75 is a double-acting ISO 15552 profile cylinder offering 628 N of push force at 0.5 MPa and 879 N at 0.7 MPa. Its 75 mm stroke is well-suited for short-travel clamping and ejection tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior.
This specific unit is configured with a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance. It utilizes PT tapered port threads and lacks a standard magnet, meaning position-sensing switches are not supported without modification.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX75 Is Used
Short-Stroke Clamping
Provides 879 N of thrust at 0.7 MPa, ideal for securely holding medium-weight workpieces during machining or welding operations.
Package Ejection
The 75 mm stroke offers rapid, compact ejection of products off a conveyor line without requiring excessive mounting space.
Gate Diverter
Delivers reliable actuation for pneumatic flap gates or diverter arms in light material handling systems.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX75 the Right Cylinder?
When sizing this 40 mm bore unit, consider the neighbouring 50 mm bore if you need greater thrust; the 50 mm version yields 982 N at 0.5 MPa compared to this model's 628 N. Conversely, a 32 mm bore provides 402 N if a lighter, more compact footprint is acceptable.
Because this is a double-acting cylinder, it requires live air pressure to both extend and retract. If your mechanism must hold a load vertically when air is exhausted or a valve is centered, the standard SAI will drift; you should specify the SAIL variant with an air-released lock or use an external rod lock. As a true ISO 15552 cylinder, it is dimensionally interchangeable with other ISO 15552 profile cylinders, matching the 40 mm bore, 75 mm stroke, PT port, and standard mounting accessories like FA flanges.
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 SAI40AX75 FAQ
