About the Airtac SAI40 Standard Air Cylinder SAI40BX750S
The AirTAC SAI40X750-S is a double-acting profile cylinder built to the ISO 15552 mounting interface, ensuring exact dimensional interchangeability for direct replacements. Operating at a 40mm bore, it generates 628N of push force and 528N of pull force at 0.5 MPa. The 750mm stroke is well-suited for automated material transfer and long-traverse robotic handling tasks.
This specific configuration includes a SUS304 stainless steel rod (material code B) for superior corrosion resistance in humid or washdown environments. It is equipped with a magnetic piston (-S) for direct integration with CMSE or DMSE sensor switches along the dual grooves on the extruded aluminum barrel. Fluid ports feature PT tapered threading.

Where the Airtac SAI40 Standard Air Cylinder SAI40BX750S Is Used
Long-Range Transfer
Drives parts across 750mm spans between machining cells without requiring intermediate stops.
Robotic Handling
Extends gripper assemblies into work zones, using the SUS304 rod to resist coolant mist.
Pallet Push-Off
Pushes empty pallets off accumulation lines where a 628N push force is sufficient.
Is the Airtac SAI40 Standard Air Cylinder SAI40BX750S the Right Cylinder?
When sizing this actuator, note that stepping down to a 32mm bore reduces the 0.5 MPa push force to 402N, while a 50mm bore increases it to 982N. The 750mm stroke is a standard length but requires careful mechanical integration; long unsupported rods are highly susceptible to bending under side loads, so an external guide rail or a fully guided cylinder should be used to prevent premature rod-bearing wear.
This model uses a G1/4 port and M12x1.25 rod threading. As a standard double-acting cylinder, it relies on live air pressure to hold its position; if pneumatic supply is lost or exhausted, the piston will drift. For suspended loads requiring fail-safe holding, specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock. Adjustable air cushions at both ends (30mm stroke length) manage end-of-stroke deceleration.
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.
