About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX270-40
The AirTAC SAIJ32X270-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 230 to 270 mm, allowing you to dial back the 270 mm nominal stroke by up to 40 mm during commissioning. In the 32 mm bore class, it delivers 402 N of push force at 0.5 MPa and uses a G1/8 port.
This unit features a SUS420J2 stainless steel rod for corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU is configured without a magnet. The rear adjuster acts purely as a travel stop to fine-tune the end position without adding external stops.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX270-40 Is Used
Machine Changeover
Dial in the exact end-stop between 230 and 270 mm when switching product sizes on a packaging line without changing the cylinder.
Fixture Positioning
Fine-tune the clamping travel during initial commissioning to ensure the SUS420J2 rod hits the exact required position.
Diversion Gates
Adjust the stroke length on sorting conveyors to accommodate different package dimensions on the fly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX270-40 the Right Cylinder?
Choose this 32 mm bore cylinder when an application requires 402 N of push force at 0.5 MPa and on-the-fly end-position tuning. The 40 mm adjustment window is ideal for product changeovers on a line, preventing the need to physically swap out a fixed-stroke SAI cylinder. If your setup needs higher force, stepping up to the 40 mm bore yields 628 N at 0.5 MPa.
Because the nominal stroke is 270 mm, the 12 mm diameter rod and M10x1.25 rod thread will carry some side load, but an external guide is recommended for long unsupported strokes. The rear adjuster only sets the travel end; it does not hold the load without live air. For true load-holding without pressure, consider an external rod lock or the SAIL series. This SAIJ model uses the reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and is dimensionally interchangeable per ISO 15552.
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 Adjustable Cylinder SAIJ32 SAIJ32AX270-40 FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers 82 kgf.
The rear adjuster screw lets you shorten the effective travel from 270 mm down to 230 mm. This allows you to set the exact end position during setup without swapping the cylinder or adding external stops.
