About the Airtac SAI40 Standard Air Cylinder SAI40X35
The AirTAC SAI40X35 is a double-acting ISO 15552 profile cylinder engineered for compact, high-cycle assignments. It supplies 628 N of push force and 528 N of pull force at 0.5 MPa, making it well-suited for short 35 mm stroke movements. The extruded aluminum barrel skips tie-rods to provide a clean, modern exterior.
This specific configuration utilizes a standard carbon steel piston rod and PT tapered port threads. Because a magnet is not specified, it operates without integrated position sensing. For high-temperature environments up to +70 C, the standard TPU seals handle the demands perfectly, though Viton (H) alternatives exist for extreme thermal needs.

Where the Airtac SAI40 Standard Air Cylinder SAI40X35 Is Used
Short-Stroke Clamping
Ideal for holding thin workpieces securely in machining or welding fixtures where a 35 mm extension is sufficient.
Package Diverting
Provides rapid actuation for routing small to medium packages on automated material handling lines.
Part Ejection
Delivers 628 N of push force at 0.5 MPa to reliably knock finished components out of press dies.
Is the Airtac SAI40 Standard Air Cylinder SAI40X35 the Right Cylinder?
Select this 40 mm bore when a 32 mm variant (providing 402 N at 0.5 MPa) lacks the necessary power for part ejection or clamping. The 35 mm stroke is optimal when full extension must happen rapidly within a confined space. Because the stroke is short, rod-bearing bending is negligible, allowing direct mounting without external guides.
If your workflow demands that the payload stays put after air pressure is removed or the valve centers, a standard SAI will drift. In those scenarios, specify the SAIL variant for an air-released lock or the BSAI bidirectional clamp-lock. This model serves as a direct dimensional drop-in replacement for any ISO 15552 cylinder sharing its 40 mm bore, 35 mm stroke, and G1/4 port interface.
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 SAI40X35 FAQ
At an operating pressure of 0.5 MPa, this 40 mm bore cylinder generates 628 N of push force and 528 N of pull force. If pressure increases to 0.7 MPa, the push force rises to 879 N.
Yes. The SAI40X35 is a genuine ISO 15552 profile cylinder, meaning its mounting dimensions are fully interchangeable with other ISO 15552 cylinders of the same bore and stroke. You must ensure your setup matches the G1/4 port size.
