About the Airtac SAI40 Standard Air Cylinder SAI40AX260
The AirTAC SAI40X260 is a double-acting ISO 15552 profile cylinder offering 628N of push force at 0.5 MPa and 879N at 0.7 MPa. Its 260mm stroke is well-suited for medium-duty positioning and handling tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior.
This specific configuration features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. It uses PT tapered port threads and lacks a piston magnet, relying purely on mechanical cushioning for end-of-stroke deceleration.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX260 Is Used
Material Diverting
Actuates routing gates on conveyor lines to sort medium-weight packages efficiently.
Clamping Fixtures
Provides reliable hold-down pressure for machining operations requiring 879N force at 0.7 MPa.
Vertical Lifting
Raises and lowers lightweight platform elevators in automated storage retrieval systems.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX260 the Right Cylinder?
If your application requires less force, stepping down to a 32mm bore yields 402N at 0.5 MPa, while moving up to a 50mm bore provides 982N. Because this 260mm stroke exceeds 300mm is not the case here, but it is close; for any longer unsupported strokes, use external guides to prevent rod-bearing bending under side loads.
This model uses a G1/4 port and supports standard ISO 15552 mounting accessories like FA flanges or LB foot brackets. Note that a standard SAI cylinder will drift if air pressure is lost; for position holding without live pressure, consider the SAIL lock variant or an external pilot-operated check valve.
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.
