About the Airtac SAI40 Standard Air Cylinder SAI40X260
The AirTAC SAI40X260 is a double-acting profile cylinder built to the ISO 15552 mounting interface standard. Delivering 628 N of push force and 528 N of pull force at 0.5 MPa, it provides reliable linear motion for medium-duty automation. The 260 mm stroke is well-suited for automated clamping, lifting, and indexing tasks.
This variant features a durable carbon steel piston rod and utilizes a PT tapered port thread for secure pneumatic connections. The extruded aluminum barrel incorporates dual-sided sensor grooves, allowing for easy mounting of CMSE or DMSE switches if position feedback is later required. Adjustable air cushions at both ends ensure smooth end-of-stroke deceleration.

Where the Airtac SAI40 Standard Air Cylinder SAI40X260 Is Used
Packaging Diverter
Provides the 628 N push force and 260 mm travel needed to route cartons smoothly between packaging lines.
Clamping Fixture
Secures workpieces during machining operations, using its adjustable end cushions to prevent impact damage.
Vertical Lifting Gate
Actuates lightweight access gates or safety barriers, benefiting from the standardized ISO 15552 mounting.
Is the Airtac SAI40 Standard Air Cylinder SAI40X260 the Right Cylinder?
Choose this 40 mm bore when an application requires more thrust than a 32 mm bore (402 N push at 0.5 MPa) but does not warrant the larger footprint of a 50 mm bore (982 N push at 0.5 MPa). The 260 mm stroke provides ample travel for packaging and material handling. Because this is a double-acting cylinder, air drives the piston in both directions.
For this 260 mm stroke, which meets the 300 mm threshold for side-load concerns, ensure the load is properly guided to prevent rod-bearing bending. Use external guide rails or a guided cylinder if the application involves heavy off-center loads. Note that standard SAI cylinders do not hold position upon air loss; if fail-safe load holding is required, consider the SAIL (air-released lock) variant or an external rod lock. This model is dimensionally interchangeable per ISO 15552, featuring a G1/4 port, and can be paired with FA/FB flange or LB foot mounting accessories.
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 SAI40X260 FAQ
At 0.5 MPa operating pressure, this 40 mm bore cylinder provides 628 N of push force and 528 N of pull force. At 0.7 MPa, the push force increases to 879 N.
Yes, the SAI40X260 is dimensionally interchangeable per ISO 15552. It shares the same mounting interface and G1/4 porting, allowing it to replace other ISO 15552 profile cylinders without major design changes.
