About the Airtac SAI40 Standard Air Cylinder SAI40AX750S
The AirTAC SAI40X750-S is a double-acting ISO 15552 profile cylinder engineered for a 750mm stroke, delivering 879N of push force at 0.7 MPa. Its extruded aluminum barrel omits tie-rods, providing a clean profile that drops directly into standardized ISO 15552 mounting interfaces.
This specific configuration includes an SUS420J2 stainless steel piston rod for enhanced corrosion resistance and a built-in magnet (-S) for position sensing. You can mount CMSE or DMSE switches directly into the sensor grooves on both sides of the barrel. It uses PT tapered G1/4 ports and adjustable air cushions at both ends to decelerate the piston smoothly.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX750S Is Used
Long-Stroke Material Handling
Pushes products or diverters across wide conveyor belts using the 750mm stroke, relying on the SUS420J2 rod to resist minor environmental moisture.
Pallet Positioning
Shifts pallets into alignment at packaging stations, using CMSE sensors in the barrel grooves to confirm extension and retraction.
Automated Assembly Transfer
Moves components between machining stations over a 750mm gap, requiring external linear guides to support the load and prevent rod bending.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX750S the Right Cylinder?
Choose this 40mm bore when an application requires the 628N push force at 0.5 MPa over a long 750mm reach; if you need less force, step down to a 32mm bore (402N at 0.5 MPa), or move up to a 50mm bore (982N at 0.5 MPa) for heavier loads. Because the stroke is 750mm, the unsupported piston rod is highly susceptible to bending under side loads. Use an external guide rail or a guided cylinder to prevent rod-bearing damage.
This model is dimensionally interchangeable with other ISO 15552 cylinders, matching the 40mm bore, 750mm stroke, G1/4 port, and standard mounting accessories like FA flanges or TC trunnions. Note that the adjustable air cushion only decelerates the piston at stroke end; it does not lock the rod. If the machine loses air pressure, the load will drift, requiring an external pilot check valve or a SAIL locking variant for secure holding.
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.
