About the Airtac SAI40 Standard Air Cylinder SAI40X10S
The AirTAC SAI40X10-S is a double-acting ISO 15552 profile cylinder engineered for ultra-short stroke demands. It provides a push force of 628 N and a pull force of 528 N at 0.5 MPa. The extruded aluminum barrel design omits tie-rods, offering a clean exterior that drops directly into standardized ISO 15552 mounting interfaces without compatibility issues.
Equipped with a magnetic piston (-S), this unit supports CMSE and DMSE reed or solid-state switches via the integrated sensor grooves on both sides of the barrel. The standard carbon steel piston rod provides robust strength for industrial automation, while the adjustable air cushions at both ends ensure smooth deceleration even at the extremes of its 30-800 mm/s operating speed range.

Where the Airtac SAI40 Standard Air Cylinder SAI40X10S Is Used
Short-Stroke Clamping
Ideal for holding lightweight workpieces securely in machining fixtures where only 10 mm of travel is required to lock the part.
Ejector Mechanism
Provides a rapid 628 N push to eject finished parts from a conveyor line immediately after a processing cycle ends.
Gate Diverter
Actuates small pneumatic sorting gates on high-speed packaging equipment, utilizing the integrated magnet for position confirmation.
Is the Airtac SAI40 Standard Air Cylinder SAI40X10S the Right Cylinder?
Selecting this 40 mm bore over the smaller 32 mm variant upgrades your push force from 402 N to 628 N at 0.5 MPa, which is critical when a short 10 mm stroke must generate immediate clamping or ejection pressure. Because 10 mm is a non-standard stroke, expect made-to-order lead times rather than off-the-shelf shipping.
For applications needing to maintain a clamp during a complete air pressure loss, remember that the standard SAI cylinder will drift and cannot hold a load. In those safety-critical scenarios, specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock cylinder instead of relying on the cushion.
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 SAI40X10S FAQ
At a standard operating pressure of 0.5 MPa, this 40 mm bore cylinder generates 628 N of push force and 528 N of pull force. At the maximum rated pressure of 1.0 MPa, it can achieve a theoretical force of up to 128 kgf.
Yes. The SAI40X10-S is built to the ISO 15552 dimensional standard, making it dimensionally interchangeable with other ISO 15552 profile cylinders of the same bore size. You can swap it directly into existing FA, FB, LB, or TC mounting footprints without altering the machine frame.
