About the Airtac SAI40 Standard Air Cylinder SAI40AX350
The AirTAC SAI40X350 is a double-acting ISO 15552 profile cylinder offering a 628 N push force at 0.5 MPa. Its 350 mm stroke provides the extended travel needed for mid-range automation tasks. The extruded aluminum barrel design omits tie rods for a clean exterior.
This specific configuration features a SUS420J2 stainless steel rod (option A) for superior corrosion resistance compared to standard carbon steel. It uses PT tapered port threads (G1/4) and lacks a piston magnet, focusing purely on mechanical actuation without sensor integration.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX350 Is Used
Material Transfer
Pushes packages or diverts products along extended conveyor lines where a 350mm reach is required.
Pallet Handling
Actuates mid-sized gating or lifting mechanisms within automated storage and retrieval systems.
Component Ejection
Ejects machined parts from a fixture over a longer distance to clear the work zone safely.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX350 the Right Cylinder?
If your application requires less force, stepping down to a 32 mm bore yields 402 N at 0.5 MPa, whereas moving up to a 50 mm bore provides 982 N. Because this 350 mm stroke creates a long unsupported rod when extended, it is highly susceptible to bending under side loads. Using an external guide rail or a guided cylinder is strongly recommended to prevent premature rod-bearing wear.
As a dimensionally interchangeable ISO 15552 cylinder, it serves as a direct replacement matching the 40 mm bore, 350 mm stroke, G1/4 port, and standard mounting accessories. Remember that the adjustable air cushions only decelerate the piston at end-of-stroke; they do not hold a load if air pressure is lost.
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 SAI40AX350 FAQ
