About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX290-100S
The AirTAC SAIJ32X290-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 402 N of push force at 0.5 MPa and features a 190-290 mm usable travel window, letting you trim up to 100 mm off the 290 mm nominal stroke during commissioning.
This variant includes an SUS420J2 stainless steel rod (code A) for improved corrosion resistance and carries a magnet (-S) for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel provides sensor grooves on both sides, and the PT tapered port threads match the standard G1/8 fitting size for this 32 mm bore.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX290-100S Is Used
Product Changeover
Dial in the 190-290 mm travel window on packaging lines to accommodate different carton sizes without physically replacing the actuator.
Machine Setup
Fine-tune the retract end-position during initial commissioning to perfectly seat components, eliminating the need for external mechanical stops.
Variable End Stops
Use the 100 mm adjustment screw to vary the stroke endpoint on the fly for light-duty testing and assembly fixtures requiring flexible positioning.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX290-100S the Right Cylinder?
Choose this 32 mm bore when you need precise end-position tuning without swapping cylinders or adding external stops; if your setup requires less force, step down is not an option below 32, but stepping up to a 40 mm bore yields 628 N push at 0.5 MPa. Because the 290 mm stroke is relatively long for this small bore, ensure you use an external guide to support the load and prevent excessive side-loading on the 12 mm rod. To match an ISO 15552 replacement, specify bore, 290 mm stroke, 100 mm adjust, PT ports, SUS420J2 rod, and the -S magnet.
Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure; for pneumatic locking without air, consider the SAIL or BSAI series instead. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR.
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 SAIJ32AX290-100S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw allows you to shorten the effective travel by up to 100 mm, creating a 190-290 mm usable stroke window. It acts as a mechanical stop and does not lock the load without live air pressure.
