About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX230-40
The AirTAC SAIJ32X230-40 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 230 mm stroke that can be fine-tuned down by up to 40 mm, giving you a precise 190-230 mm usable travel window during commissioning. Delivering 563 N of push force at 0.7 MPa, it fits light-duty positioning tasks perfectly.
This variant features 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, though this specific SKU is configured without a magnet. It uses a PT tapered G1/8 port and relies on variable air cushions at both ends to decelerate the load smoothly.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX230-40 Is Used
Machine Changeover
Dial in the 190-230 mm travel window during product size changes to set new retract endpoints without replacing hardware.
Assembly Calibration
Fine-tune the final end position at commissioning to achieve exact contact depth on light-duty pressing tasks.
Variable Stops
Adjust the retract stop on the fly for conveyor diverters or indexing mechanisms that handle varying package sizes.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX230-40 the Right Cylinder?
Select this 32 mm bore when an application requires precise end-position tuning without the hassle of swapping cylinders or adding external stops. If your setup needs more force, stepping up to the 40 mm bore increases push force to 879 N at 0.7 MPa. The rear adjuster on this SAIJ acts purely as a travel stop and does not hold the load without live air; for true load-holding, consider the SAIL or BSAI series.
To replace an existing ISO 15552 cylinder, match the 32 mm bore, 230 mm nominal stroke, 40 mm adjustment range, PT G1/8 port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the 230 mm stroke is relatively long for this compact bore, ensure adequate external guidance to prevent excessive side-loading on the 12 mm rod.
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 SAIJ32AX230-40 FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 40 mm, creating a 190-230 mm travel window. It acts as a physical stop to set the end position and works alongside the air cushions for deceleration.
At 0.7 MPa operating pressure, it provides 563 N of push force and 345 N of pull force. The maximum push force is 724 N at 0.9 MPa.
