About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX240-10S
The AirTAC SAIJ32X240-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 230-240 mm usable travel window, allowing you to trim the effective stroke by up to 10 mm during commissioning without swapping the cylinder or adding external stops. In this -S configuration, the piston includes a magnet for direct compatibility with AirTAC CMSE reed and DMSE electronic sensors.
Driven by a 32 mm bore, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa. The rod utilizes SUS420J2 stainless steel (code A) for enhanced corrosion resistance, and the extruded aluminum barrel features sensor grooves on both sides. The rear adjuster acts purely as a travel stop to fine-tune the retract position; it does not lock the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX240-10S Is Used
Machine Changeover
Dial in the exact 230-240 mm retract distance instantly when switching product sizes, eliminating the need to fabricate external shims.
End-Stop Calibration
Fine-tune the final resting position during initial commissioning to achieve precise mechanical alignment without replacing the actuator.
Sorting Diverters
Adjust the stroke on a 32 mm bore diverter to accommodate varying package depths on the fly while maintaining 402 N of pushing force.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX240-10S the Right Cylinder?
Choose this 32 mm bore when an application requires precise end-position tuning within a 230-240 mm travel window. If your setup needs less force, stepping down is not an option below 32 mm in this series, but stepping up to a 40 mm bore yields 628 N of push force at 0.5 MPa. The adjustable stroke is ideal for product changeovers on a line where a fixed-stroke SAI cylinder would require mechanical spacers.
For an exact ISO 15552 replacement, match the 32 mm bore, 240 mm stroke, PT tapered port threads, and the -S magnet option. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the stroke is 240 mm, ensure external guides are used to prevent excessive side-loading on the 12 mm rod. If the machine requires true load-holding without continuous air pressure, integrate an AirTAC SAIL or BSAI cylinder 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 SAIJ32AX240-10S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach a maximum push force of 724 N at 0.9 MPa.
The rear adjuster screw allows you to shorten the 240 mm nominal stroke by up to 10 mm, creating a 230-240 mm usable travel window. The adjuster functions as a mechanical stop for end-position tuning and does not lock the load without live air pressure.
