About the Airtac SAI40 Standard Air Cylinder SAI40AX300
The AirTAC SAI40X300 is a double-acting ISO 15552 profile cylinder offering a 628N push force at 0.5 MPa. Its extruded aluminum barrel design omits tie rods, providing a clean exterior that drops directly into standardized ISO 15552 mounting interfaces.
This 300mm stroke variant ships with a SUS420J2 stainless steel rod (option A) for superior corrosion resistance compared to standard carbon steel. It utilizes PT tapered port threading and lacks a standard piston magnet, making it ideal for basic pneumatic driving tasks where position sensing is not required.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX300 Is Used
Material Diversion
Drives 300mm linear pushers to divert medium-weight packages across conveyor belts without requiring magnetic position feedback.
Clamp Actuation
Extends 300mm to engage secondary clamping arms on machining fixtures, utilizing the SUS420J2 rod to resist mild coolant splashing.
Pallet Handling
Pushes empty pallets into staging lanes where the 628N force at 0.5 MPa is sufficient to overcome friction over short distances.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX300 the Right Cylinder?
At 0.5 MPa, the 40mm bore generates 628N of push force. If your application requires less force, stepping down to the 32mm bore yields 402N. For heavier loads, the 50mm bore provides 982N. Because this model features a 300mm stroke, the extended rod is susceptible to bending under side loads; utilizing an external guide rail or a guided cylinder will prevent premature wear on the rod-bearing assembly.
As a genuine ISO 15552 profile cylinder, this unit is dimensionally interchangeable with other ISO 15552 cylinders. To replicate this exact configuration, specify a 40mm bore, 300mm stroke, PT G1/4 port, FA/FB flange or LB foot mounting, and no magnet (-S omitted). Note that standard pneumatic cushions only decelerate the piston at end-of-stroke; they do not hold loads. If pressure drops, use the SAIL lock variant to prevent drifting.
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 SAI40AX300 FAQ
