About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX275-40
The AirTAC SAIJ32X275-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a usable travel window of 235 to 275 mm, allowing you to dial in the exact retract position during commissioning without adding external stops.
This specific SKU is configured with a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. The rear adjuster acts purely as a travel stop to fine-tune the end position, not as a lock, so live air pressure is required to hold the load in place.

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 SAIJ32BX275-40 Is Used
Machine Setup Tuning
Dial in the exact 235 to 275 mm retract position during initial commissioning without swapping out the entire cylinder or adding external mechanical stops.
Product Changeover
Quickly adjust the end-of-stroke stop up to 40 mm when a production line switches to a new product size, minimizing downtime and retooling effort.
Corrosive Assembly Tasks
Leverage the SUS304 stainless steel rod for light-duty pushing or pulling in environments where standard carbon steel rods would rust or degrade.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX275-40 the Right Cylinder?
Choose this 32 mm bore if your application requires precise mechanical end-position tuning at setup or during product changeovers. The adjustable rear stopper saves time over a fixed-stroke SAI cylinder by allowing on-the-fly travel adjustments. Because the 275 mm stroke is relatively long for this compact bore, an external guide is recommended to prevent excessive side-loading on the rod.
For an exact ISO 15552 dimensionally interchangeable replacement, match the 32 mm bore, 275 mm stroke, 40 mm adjustment range, PT port thread, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that this standard configuration does not include a magnet for position sensing. If position holding without live air is required, consider the SAIL or BSAI series instead of relying on the adjuster.
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 SAIJ32BX275-40 FAQ
The rear adjuster screw allows you to mechanically shorten the effective travel from the nominal 275 mm down to 235 mm. This stopper fine-tunes the end position but does not lock the load; live air pressure is still required to maintain position.
