About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX290-100
The AirTAC SAIJ32X290-100 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 190-290 mm usable travel window, allowing you to dial back the 290 mm nominal stroke by up to 100 mm during machine commissioning. Delivering 402 N of push force at 0.5 MPa, it suits lighter-duty positioning tasks.
This variant uses a SUS420J2 stainless steel rod for improved corrosion resistance and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides. The rear adjuster acts strictly as a travel stop for end-position tuning and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX290-100 Is Used
Product Changeover
Dial in the 190-290 mm travel window during format size changes without physically swapping the cylinder or adding external mechanical stops.
End-Position Tuning
Fine-tune the retract end-stop during machine commissioning to perfect the 290 mm nominal stroke alignment for delicate picking operations.
Light-Load Routing
Actuate lightweight diverter gates using the 402 N push force, adjusting the travel distance easily as conveyor layouts evolve.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX290-100 the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N push force at 0.5 MPa and on-the-fly end-stop tuning. If your setup demands greater thrust, stepping up to the 40 mm bore yields 628 N. The 100 mm adjustment range is ideal for product changeovers, replacing fixed-stroke SAI cylinders when external stops are impractical. For load-holding without continuous air, consider an SAIL or BSAI cylinder instead.
With a 290 mm stroke, the 12 mm rod requires external guidance to prevent side-load damage. This SAIJ model accepts Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting the FB, CA, CB, and CR options. It operates at 30-800 mm/s and is dimensionally interchangeable per ISO 15552.

- ✓ 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 SAIJ32AX290-100 FAQ
The rear adjuster screw lets you shorten the effective travel from the 290 mm nominal stroke down to 190 mm, creating a 100 mm adjustable window. It acts purely as a mechanical stop to fine-tune the retract position and does not lock the load without live air.
At 0.5 MPa operating pressure, it provides 402 N of push force and 345 N of pull force. The maximum thrust is 82 kgf at 1.0 MPa.
