About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX280-40
The AirTAC SAIJ32X280-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 280 mm stroke that can be fine-tuned down by up to 40 mm, giving operators a precise 240-280 mm usable travel window during commissioning.
This model uses a SUS420J2 stainless steel rod (material code A) for improved corrosion resistance compared to standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. Note that the rear adjuster acts strictly as a travel stop to set deceleration, not as a lock, so the cylinder cannot hold a load without live air pressure.

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 SAIJ32AX280-40 Is Used
Product Changeovers
Dial in the 240-280 mm travel window during format changes on packaging lines without physically swapping cylinders or adding external mechanical stops.
End-Position Tuning
Fine-tune the retract end position at machine commissioning to perfect the alignment of lighter 32 mm bore actuators handling delicate components.
Variable Stops
Provide adjustable physical end stops for diverters or gates on conveyors, allowing operators to quickly modify the stroke length for different package sizes.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX280-40 the Right Cylinder?
If your setup demands higher thrust, stepping up to the 40 mm bore yields 628 N. The adjustable stroke is ideal for product changeovers on a line, letting you dial in the 240-280 mm travel window without swapping the cylinder. For load-holding without continuous air pressure, consider the SAIL or BSAI variants instead.
Because this unit features a 280 mm stroke, the 12 mm rod and M10x1.25 thread should be paired with an external guide to prevent excessive side loading. It is dimensionally interchangeable per ISO 15552. When replacing, match the 32 mm bore, 280 mm stroke, 40 mm adjustment, PT tapered port thread, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). As no magnet is specified, position sensing via CMSE or DMSE switches is not supported on this specific SKU.
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 SAIJ32AX280-40 FAQ
The maximum thrust is 82 kgf at 1.0 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke by up to 40 mm. This creates a usable travel window of 240-280 mm, allowing precise end-position tuning without changing the cylinder.
