About the Airtac SAI40 Standard Air Cylinder SAI40AX15
The AirTAC SAI40X15 is a double-acting ISO 15552 profile cylinder engineered for precise short-stroke actuation. It delivers a push force of 628 N and a pull force of 528 N at 0.5 MPa. Because the stroke is only 15 mm, it is classified as a non-standard, made-to-order configuration tailored for extremely tight spaces.
This variant features an SUS420J2 stainless steel rod (material code A) for superior corrosion resistance compared to standard carbon steel. It uses PT tapered port threads and lacks a magnet (-S), meaning it is optimized for pure mechanical force transfer without the need for Hall-effect position sensing.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX15 Is Used
Short-Stroke Clamping
Ideal for compact clamping stations where a 15 mm extension securely grips parts without consuming excessive machine footprint.
Valve Actuation
Provides rapid, high-force actuation for process valves in confined assemblies where a standard 25 mm stroke would bottom out.
Ejector Mechanisms
Used in packaging lines to quickly eject small components over a tight 15 mm travel distance with reliable 628 N of push force.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX15 the Right Cylinder?
When upgrading from this bore, stepping up to the 50 mm bore increases the 0.5 MPa push force to 982 N, while dropping down to the 32 mm bore reduces it to 402 N. Because the 15 mm stroke is non-standard, ensure your machine cycle allows for the custom manufacturing lead time. As a double-acting cylinder, it requires continuous air pressure to hold its position; if the air supply drops, the load will drift. For applications requiring dead-stop holding without live pressure, consider the SAIL locking variant or an external pilot-operated check valve. To ensure proper interchangeability, match the 40 mm bore, 15 mm stroke, PT port thread, and required mounting accessory (such as an FA flange) when replacing other ISO 15552 profile cylinders.
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 SAI40AX15 FAQ
At a 0.5 MPa operating pressure, the SAI40X15 generates 628 N of push force and 528 N of pull force. At 0.7 MPa, the push force increases to 879 N.
Yes, as a genuine ISO 15552 profile cylinder, its mounting dimensions are standardized. It serves as a direct replacement for other ISO 15552 cylinders with a 40 mm bore, provided you match the PT port and 15 mm stroke.
