About the Airtac SAI40 Standard Air Cylinder SAI40AX450
The AirTAC SAI40X450 is a double-acting ISO 15552 profile cylinder engineered to deliver 628 N of push force at 0.5 MPa and 879 N at 0.7 MPa. Its 450 mm stroke provides the extended travel needed for automated machinery routing and part ejection. The extruded aluminum barrel design omits tie-rods, presenting a clean exterior that drops into existing ISO 15552 mounting interfaces.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in humid production environments. It utilizes PT tapered port threads and lacks the -S magnet option, meaning it is optimized for purely mechanical actuation without external position sensing.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX450 Is Used
Automated Part Ejection
Uses the 450mm stroke to push completed parts off a conveyor belt into a packaging chute with 879N of force at 0.7MPa.
Long-Reach Material Handling
Extends across a wide machine bed to transfer pallets or trays between processing stations without requiring intermediate robotics.
Packaging Press Mechanism
Actuates a secondary sealing or folding press over extended distances where a long stroke is required to clear tooling during setup.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX450 the Right Cylinder?
When sizing this 40 mm bore model, stepping down to a 32 mm bore reduces the 0.5 MPa push force to 402 N, while stepping up to a 50 mm bore increases it to 982 N. Because the 450 mm stroke exceeds the 300 mm threshold, the unsupported rod is highly susceptible to bending under side loads; utilize an external guide rail or a dedicated guided cylinder to prevent premature rod-bearing wear.
As a standard double-acting actuator, the SAI40X450 relies on live air pressure to move and hold its load. If your application requires true position holding during air loss or valve centering, the SAIL pneumatic lock variant or an external pilot-operated check valve is necessary. The adjustable air cushions at both ends only serve to decelerate the piston near stroke end, not to lock it in place.
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 SAI40AX450 FAQ
The SAI40X450 generates a push force of 628 N at 0.5 MPa and 879 N at 0.7 MPa, with a pull force of 528 N at 0.5 MPa.
Yes, as a genuine ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders of the same bore and stroke, using standard FA, LB, or TC mounting accessories.
