About the Airtac SAI40 Standard Air Cylinder SAI40AX750
The AirTAC SAI40X750 is a double-acting ISO 15552 profile cylinder offering a 750mm stroke. It provides 628N of push force and 528N of pull force at 0.5 MPa, making it well-suited for medium-duty linear actuation over extended distances. The extruded aluminum barrel omits tie rods, presenting a clean exterior that drops directly into ISO 15552 mounting interfaces.
This specific configuration incorporates a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. Fluid is clean air filtered to 40 um, operating at 30-800 mm/s. It utilizes PT tapered port threading and lacks a standard magnet, meaning position sensing via CMSE or DMSE switches would require a custom -S suffix build.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX750 Is Used
Extended Transfer Lines
Ideal for pushing pallets or product between distant workstations over a 750mm travel distance.
Material Handling Gates
Actuates medium-sized sorting gates or diverters requiring 628N of push force at 0.5 MPa.
Long-Stroke Assembly Presses
Drives tooling heads that must travel significantly before applying clamping or joining pressure.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX750 the Right Cylinder?
When sizing this actuator, stepping down to a 32mm bore reduces the 0.5 MPa push force to 402N, while moving up to a 50mm bore increases it to 982N. Because this unit features a 750mm stroke, the extended rod is highly susceptible to bending under side loads. Implementing an external guide rail or selecting a guided cylinder variant is strongly recommended to prevent premature rod-bearing wear.
This SAI40X750 model is dimensionally interchangeable per ISO 15552 standards. To match this exact unit for replacement, specify a 40mm bore, 750mm stroke, G1/4 port size, PT thread type, and SUS420J2 rod material. Note that standard SAI cylinders do not hold loads pneumatically; if pressure drops, the piston drifts. For position holding, consider the SAIL air-released lock variant or an external rod lock.
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 SAI40AX750 FAQ
At 0.5 MPa, the SAI40X750 generates 628N of push force and 528N of pull force. At 0.7 MPa, the push force increases to 879N.
Yes. As a genuine ISO 15552 profile cylinder, its mounting dimensions are standardized. You can drop it into existing ISO 15552 interfaces as long as the 40mm bore, 750mm stroke, and G1/4 port match your setup.
