About the Airtac SAI40 Standard Air Cylinder SAI40X260S
The AirTAC SAI40X260-S is a double-acting ISO 15552 profile cylinder engineered to deliver 628 N of push force at 0.5 MPa. Its 260 mm stroke makes it highly suitable for medium-travel material handling and robotic gating tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that simplifies mounting and sensor placement.
Equipped with a magnetic piston, this unit supports position detection via CMSE or DMSE series switches installed in the integrated sensor grooves on both sides of the barrel. It features a standard carbon steel piston rod and a PT tapered port thread, ensuring robust and leak-free pneumatic connections.

Where the Airtac SAI40 Standard Air Cylinder SAI40X260S Is Used
Package Diverting
Provides reliable actuation for diverting medium-weight packages on sorting lines, utilizing the 260 mm stroke to clear adjacent conveyor lanes.
Clamping Fixtures
Delivers 628 N of push force at 0.5 MPa to secure workpieces during light machining or welding operations within automated cells.
Pallet Gate Control
Actuates safety gates and lightweight access doors in warehouse environments, where the magnetic piston allows automated position feedback.
Is the Airtac SAI40 Standard Air Cylinder SAI40X260S the Right Cylinder?
Selecting this 40 mm bore over the smaller 32 mm variant increases your 0.5 MPa thrust from 402 N to 628 N, providing a substantial uplift in work capacity without a massive footprint increase. If your application requires even greater clamping force, stepping up to the 50 mm bore yields 982 N. The 260 mm stroke falls well within the 1200 mm standard maximum, ensuring rapid availability.
With a stroke of 260 mm, the extended rod is subject to bending under side loads, so utilizing an external guide rail or a fully guided cylinder is recommended to prevent premature rod-bearing wear. Note that this standard cylinder relies on live air pressure to move; it does not hold position if air is lost. For fail-safe load holding, consider the SAIL or BSAI locking variants. This model is dimensionally interchangeable per ISO 15552, accepting standard FA/FB flanges and TC trunnion mounts.
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 SAI40X260S FAQ
At a standard operating pressure of 0.5 MPa, the 40 mm bore generates 628 N of push force and 528 N of pull force. It can reach 879 N at 0.7 MPa.
Yes. The SAI40X260-S is built to the ISO 15552 standard, making its mounting interface and center-to-center dimensions fully interchangeable with other ISO 15552 profile cylinders.
