About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX270-50
The AirTAC SAIJ32X270-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that allows you to trim the nominal 270 mm travel back by up to 50 mm. This creates a precise 220-270 mm usable window, enabling exact end-position tuning at commissioning without swapping out the unit or adding external stops. Built with a SUS304 stainless steel rod, it provides excellent corrosion resistance for demanding environments.
The extruded aluminum barrel includes dual sensor grooves for mounting CMSE reed or DMSE solid-state switches, though this specific SKU is configured without a magnet. Its robust M10x1.25 rod thread handles standard loads, but the 270 mm stroke warrants an external guide to prevent excessive side-loading on the piston rod.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX270-50 Is Used
End-Stop Calibration
Dial in the exact 220-270 mm travel window during machine commissioning to perfect positioning without physically swapping the cylinder.
Product Changeover
Quickly adapt the stroke length on a packaging line for different carton sizes by adjusting the rear stopper screw up to 50 mm.
Assembly Positioning
Fine-tune the extension end-point for delicate pressing or seating tasks where a fixed 270 mm stroke would apply excessive force.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX270-50 the Right Cylinder?
Choose this adjustable-stroke model over a fixed SAI cylinder when your application requires frequent product changeovers or exact end-stop calibration without mechanical rework. Conversely, larger bores like the 63 mm offer 1559 N but require more space.
This SAIJ32X270-50 is dimensionally interchangeable with ISO 15552 cylinders. To match this configuration for an ISO replacement, specify a 32 mm bore, 270 mm stroke, 50 mm adjustment range, PT port thread, SUS304 (B) rod material, and no magnet. Remember that the rear adjuster functions only as a travel stop; it does not hold the load without live air pressure. For load-holding requirements without continuous air, consider the SAIL or BSAI series. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ32BX270-50 FAQ
At the maximum 1.0 MPa pressure, it delivers up to 82 kgf.
The rear adjuster screw acts as a mechanical stop that can shorten the 270 mm nominal stroke by up to 50 mm, providing an effective travel window of 220-270 mm. It only sets the end position and does not lock the load without live air pressure.
